Question

A number cube is rolled and a coin is flipped. Predict how many times you would get heads and a number less than 3 in 240 trials.



60
40
30
20

Answer 1

Less than 3 = 1 or 2 = 1/3 probability

Heads = 1/2

The probability of both/all events occurring is found by multiplying the individual events.

1/2 * 1/3 = 1/6

1/6 of 240 = ?

Answer 2

1/6 0f 240 is equal to 40
