Question

Find the probability of getting two heads and two tails when four coins are tossed.

Answer 1

Probability of getting a head $=\frac{1}{2}$

Probability of getting a tail $=\frac{1}{2}$

Required probability $=\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}=\frac{1}{16}$
