Question

The probability of getting an even number, when a die is thrown once, is : 

Options

• (A)`1/2`

• (B)`1/3`

• (C)`1/6`

• (D)`5/6`

Answer 1

When a die is thrown once, the sample space is given by, S = {1, 2, 3, 4, 5, and 6}

Then, the event, E of getting an even number is given by, E = {2, 4, and 6}

∴ Probability of getting an even number = P (E)`thereforeP(E)\text{Number of favourable outcomes}/\text{Number of all possible outcomes}=3/6=1/2`

The correct answer is `1/2` which is given by option A.
