Question

if a die is rolled once, then the probability of obtaining a number greater than 3 is​

Answer 1

Numbers above 3 are 4,5,6.

Favourable outcomes = 3.

Total outcomes = 6.

Probability = 3/6

= 1/2

= 0.5

Answer 2

The probability of obtaining a number greater than 3 is​ $\dfrac{1}{2}$.

Step-by-step explanation:

When a dice are thrown.

All possible outcomes are:

{1, 2, 3, 4, 5 and 6}

Total number of all possible outcomes = 6

Let E be the event of getting that the number greater than 3.

The favorable outcomes are

4, 5 and 6

Number of favorable outcomes = 3

∴ P(E) = /($\dfrac{Number of favorable outcomes}{Total number of all possible outcomes)}$

∴ P(E) = $\dfrac{3}{6}$ = $\dfrac{1}{2}$

Hence, the probability of obtaining a number greater than 3 is​ $\dfrac{1}{2}$.
