• A. 0
• B. $\frac{1}{2}$
• C. $\frac{3}{4}$
• D. 1

Answer 1

The correct option is D

1

The probability of getting a head when a coin is tossed once is $\frac{1}{2}$ and the probability of getting a tail when a coin is tossed once is $\frac{1}{2}$. Hence the sum of probabilities of getting a head and getting a tail when a coin is tossed once is 1.
