Question

A die is rolled once. Then the probability of getting a 7 is

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

Answer 1

The correct option is C $0$

Probability of an event, P(E)
= $\frac{Numberoffavourableoutcomes}{Numberoftotalpossibleoutcomes}$

Possible outcomes on a single roll of a die are 1, 2, 3, 4, 5 and 6. Therefore, the chance of getting a 7 (favourable outcome) on rolling the die once is 0. Thus, the probability of the event is 0 or it is an impossible event.
