Solution

The correct option is A 1
The sum of probabilities of all outcomes in an experiment = 1.

For example, if we toss a coin there are two possibilities either heads or tails .

Probability of head is $\frac{1}{2}$ and probability of tail is $\frac{1}{2}$ .

Sum of all probabilities = $\frac{1}{2} + \frac{1}{2} = 1$ .
