Question

If three coins are tossed then find the probability of the events of getting exactly one tail.

• A. $\frac{1}{4}$
• B. $\frac{3}{8}$
• C. $\frac{1}{2}$
• D. $\frac{5}{8}$

Answer 1

The correct option is B $\frac{3}{8}$

A coin tossed three times sample space $=(H,H,H),(H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H),(T,T,T)$
favourable outcomes for Exactly on tail $=3$
Probability = $\frac{3}{8}$
