Question

Find the probability of getting a head when a coin is tossed in air.

• A. 1/2
• B. 1/5
• C. 1/3
• D. 1/4

Answer 1

The correct option is A

1/2

The possible outcomes of tossing a coin are heads or tails. So, the number of possible outcomes is 2 and the number of favourable outcomes is just 1.

Let E be the event of getting a head

P(E) = $\frac{\text{Number of outcomes favorable to E}}{\text{Total number of outcomes}}$ = $\frac{1}{2}$
