Question

An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in
succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 7.
Event B: The sum is an odd number.

Answer 1

Answer:

Event A：15/36

Event B：18/36

Step-by-step explanation:

We can use a table for this question，the two succession are independent so we can see it as two dice rolling at one time.

Then we just need to find out the sum which is required.

Event A: 15÷36 because there are 15 sum greater than 7 and 36 total outcomes.

Event B: 18÷36
