Guys, does anyone know the answer?

get given that p is a non-negative integer, which of these gives positive integers that are multiple of 5? from screen.

## python

The program should work as follow: Please type in a number: 5 1 5 2 4 3 My code doesn't do the same. I think there is should be the 2nd loop, but I don't really understand how can I do it. Could you ## How to write the program that prints out all positive integers between 1 and given number , alternating between the two ends of the range?

The program should work as follow:

Please type in a number: 5

1 5 2 4 3

My code doesn't do the same. I think there is should be the 2nd loop, but I don't really understand how can I do it. Could you possibly give me a hint or advice to solve this task. Thanks. My code looks like this:

num = int(input("Please type in a number:"))

n=0 while num>n: a = num%10 num -= a num = num/10 print(a) n = n + 1 print(n)

2 This should work:

num = int(input("Please type in a number:"))

number_list = [i+1 for i in range(num)]

while number_list:

print(number_list.pop(0))

number_list.reverse()

Thanks! I'm beginner in python and stucked with this type of tasks. How it possible to change this code that it shows the sequence in different order like 2 1 4 3 5 (vertically). –

Cute, but the degree of head-scratching required seems excessive for this problem. This feels like a perl solution.... –

Not the most space-efficient way, but if the number is relatively small, an easy approach is to build a list and just pop off either end in turn:

nums = list(range(1, int(input("Please type in a number:"))+1))

while nums: print(nums.pop(0)) if nums: print(nums.pop()) Share Improve this answer

Minimizing the amount of state to keep track of. For a linear-time/constant-space solution I'd use range and zip_longest but that feels out of scope for a beginner question :P –

Seemingly the most memory efficient way would be to use itertools.zip_longest and ranges:

from itertools import zip_longest

n = int(input("Please type in a number: "))

for lower, upper in zip_longest(range(1, n // 2 + 1), range(n, n // 2, -1)):

if lower: print(lower) print(upper) Share Improve this answer

This is a cute way to do it:

l = list(range(1,6))

def index_generator():

while True: yield 0 yield -1

index = index_generator()

result = [] while l:

result.append(l.pop(next(index)))

You have nine integers, none of which is divisible by 3. What is the probability that the sum of those 9 integers is divisible by 9 by 3?

If you ask about divisibility of the sum by 3, it can be found like this:

First, we have to ask what does “probability” mean in the context of infinite set of integers. But since we are only interested in divisibility by 3, we can use a naive approach that there is 1/3 chance a randomly chosen integer will be divisible by 3, 1/3 that it will give remainder 1 when divided by 3, and 1/3 that it will give remainder 2.

Since none of our integers is divisible by 3, they all give remainder when divided by 3. This remainder will be 1 or 2, with probability 1/2 for each.

We have 9 integers, so there’s 51

What is the probability that a randomly chosen positive two-digit integer is a multiple of 3?

I’m going to assume ‘randomly chosen’ to mean ‘every two digit number from

10 10 to 99 99

has an equal likelihood of being chosen’. (Note that it might mean other things, so it’s best to define your probability distribution precisely.)

With that out of the way, the two digit numbers that are divisible by

3 3 are 12,15,18,…,99 12,15,18,…,99

, of which there are

30 30

(how do I know this?). Since there are

90 90

two-digit numbers in all (how do I know this?), the probability of choosing a two-digit number ‘at random’ (with the meaning described above) is

30 90 = 1 3 3090=13 . Phil Scovis

If all positive integers are possible outcomes, what is the probability that a number chosen at random will be divisible by 5 and 11?

The common expression “chosen at random” is usually interpreted to mean “with a uniform distribution”.

You cannot have a uniform distribution with infinite support. This may seem counter-intuitive, but this is a mathematical fact. Assuming a uniform distribution with infinite support leads to paradoxes such as the Envelope Paradox

, and being sloppy with what distribution you are using leads to things like the Bertrand Paradox

.

However, we can interpret your question in ways that make more sense. For example: In the limit as x approaches infinity, what is the probability that a number chosen unif

So, n(S) = 40

First qualifier = Q1: non negative integers less than 5. So, Q1 = {0, 1, 2, 3, 4}. Thus, n(Q1) = 5.

Second qualifier = Q2: integers less than 40 and not smaller than 5 those are divisible by either 3 or 4. M3: Those divisible by 3, M4: Those divisible by 4. Now, M3 = {6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39}, M4 = {8, 12, 16, 20, 24, 28, 32, 36} and (M3 intersect M4) = {12, 2

Correct option is D)

When we add positive integer and negative integer then it is not necessary that result would be negative integer. It can be positive integer also

For eg- (+8)+(−6)=2. Hence the p statement is false.

When we add two negative integers, we will always get negative integer.

For eg- (−7)+(−9)=−16. Hence q statement is also false
