Answer:

The probability is
(5)/(16)

Explanation:

Given is that a fair coin is tossed 5 times in a row.

This gives total number of outcomes as =
2*2*2*2*2=32

As its needed that heads comes exactly 2 times, so favorable outcomes are = 5C2


(5!)/(2!(5-2)!)

Solving this we get 10

Therefore, the probability of getting heads exactly 2 times is =


(10)/(32) or


(5)/(16)
