Question : 50

Total: 62

Solution:

Concept:

For two independent events, multiply their individual probabilities.

Explanation:

The probability of getting a tail on the coin is

\frac{1}{2}

The even numbers on a die are

2

4

, and

6

So the probability of an even number on the die is

\frac{3}{6} = \frac{1}{2}

Since the events are independent, multiply the probabilities.

P(\text{tail and even}) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}

Answer:

\frac{1}{4}
