Open in App Solution
On tossing two coins, following outcomes can be observed:
{ ( H , H ) , ( T , T ) , ( H , T ) , ( T , H ) }
Therefore, there are total of
4 possible outcomes.
Now, favourable outcomes are
{ ( H , H ) , ( H , T ) , ( T , H ) }
Therefore, no. of favourable outcomes are
3
Hence, P(Getting atleast one head)
= 3 4 Suggest Corrections 109
