    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
