    Question

    An unbiased die is tossed. Find the probability of getting a prime number.

    Open in App Solution

    Step 1: Finding the total number of outcomes and the number of favourable outcomes

    The sample space when an unbiased die is tossed is

    {1, 2, 3, 4, 5, 6} .

    So, the total number of outcomes are

    6 .

    A prime number is one that has two factors -

    1 and itself.

    The prime numbers are

    2, 3, 5 .

    So, the number of favorable outcomes are

    3 .

    Step 2: Finding the probability of getting a prime number

    ⇒Probability =Number of favorable outcomesTotal number of outcomes

    ⇒P(prime number)=36 ∴P(prime number)=12

    Hence, the probability of getting a prime number is

    12 . Suggest Corrections 0
