Question

Two dice are rolled. what is the probability of having both faces the same (doubles) or a total of 4? round to the nearest hundredth.

Answer 1

The probability is 0.25.

There are a total of 36 outcomes in the sample space for rolling 2 dice.

Out of these, there are 6 ways to get doubles (1 and 1, 2 and 2, 3 and 3, 4 and 4, 5 and 5, 6 and 6).

There are also 3 ways to get a total of 4:  1 and 3, 2 and 2, 3 and 1.

Together this gives us 9/36 = 0.25.

Answer 2

The probability both faces the same (doubles) or a total of 4 is 0.22

What is probability?

Probability is the likelihood or chance that an event will occur.

• Probability = Expected outcome/Total outcome

If Two dice are rolled, the total outcome will be 6^2 = 36

If both faces the same (doubles) or a total of 4, then the expected outcomes will be:

n(E) = {(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6), (1, 3), (3, 1)}

Pr(both faces the same (doubles) or a total of 4) = 8/36 = 0.22

Hence the probability both faces the same (doubles) or a total of 4 is 0.22
