Question

A coin is tossed $200$ times and head appeared $120$ times. The probability of getting tail is

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

Answer 1

The correct option is A $\frac{2}{5}$

A coin tossed $200$ times.

Total number of times head appeared: $120$

Probability of getting head: $P\left(H\right)=\frac{120}{200}=\frac{3}{5}$

Probability of getting tail: $P\left(T\right)=1-P\left(H\right)=1-\frac{120}{200}=1-\frac{3}{5}=\frac{2}{5}$
