Question

A coin is tossed 240 times and head obtained 160 times. Now, if a coin is tossed at random, what is the probability of getting a tail?

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

Answer 1

The correct option is D $\frac{1}{3}$

A coin tossed 240 times.
Total number of times head appeared = 160
Probability of getting head P(H) = $\frac{160}{240}=\frac{2}{3}$
Probability of getting tail P(T) = 1 - P(H) = $1-\frac{2}{3}=\frac{1}{3}$
So, option (b) is the correct answer.
