Question

A fair coin is tossed independently four times. The probability of the event “the number of times heads show up is more than the number of times tails show up" is
1. 1/16
2. 1/8
3. 1/4
4. 5/16

Answer 1

Correct Answer - Option 4 : 5/16

Sample space contains 2⁴ = 16 elements. 

The favorable events are:

{H,H,H,T}, {H,H,T,H}, {H,T,H,H}, {T,H,H,H}, {H,H,H,H}. 

There are 5 possibilities,

hence the required probability is: 5/16.
