Answer:

The probability is [tex]\frac{5}{16}[/tex]

Step-by-step explanation:

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

This gives total number of outcomes as = [tex]2\times2\times2\times2\times2=32[/tex]

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

[tex]\frac{5!}{2!(5-2)!}[/tex]

Solving this we get 10

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

[tex]\frac{10}{32}[/tex] or

[tex]\frac{5}{16}[/tex]
