Question

Find the probability of getting two heads when five coins are tossed.

• A. $\frac{1}{2}$
• B. $\frac{5}{16}$
• C. $\frac{3}{9}$
• D. none of these

Answer 1

The correct option is B $\frac{5}{16}$

Number of ways of getting two heads = $5_{C_2}=10$

Total number of ways = $2^5$

P(two heads)$=\frac{10}{32}=\frac{5}{16}$
