Question

A coin is tossed 200 times and heads appeared 120 times. What is the probability of getting a tails in this experiment?

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

Answer 1

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

Total number of times the coin is tossed = 200
Number of times heads appeared = 120
$\therefore$ number of times tails appeared = 200-120 = 80
Thus, probability of getting a tails is:-
$P\left(A\right)=\frac{80}{200}=\frac{2}{5}$
