Question

Three coins are tossed together. The probability of getting exactly two heads is-

• A. $\frac{5}{8}$
• B. $\frac{3}{8}$
• C. $\frac{1}{8}$
• D. None of these

Answer 1

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

Three coins are tossed.

Thus possible outcomes are :
(H, H, T), (H, H, H), (H, T, H), (H, T, T), (T, H, T), (T, H, H), (T, T, H), (T, T, T).
Favorable cases $=$ $3$, Required probability $=$ $\frac{3}{8}$
