Question

Laurissa rolls two number cubes, each with the numbers 1 through 6. Larissa adds the numbers that appear on the roll.Which two sums have an equal chance of occurringA. 3 and 11B. 4 and 7C. 5 and 8D. 6 and 9

Answer 1

There are two number cubes.

Each has numbers 1 to 6

The probability of getting a number in a single cube after rolling is;

Geting a 1 is 1/6

Geting a 2 is 2/6

Geting a 3 is 3/6

Geting a 4 is 4/6

Geting a 5 is 5/6

Getting a 6 is 6/6

Checking the sums that have an equal change of occuring will mean that you check both cubes , identify the number occuring and finding the sum

So in this case;

A : 3 and 11 ------where one cube will give you 2 and 1 to get 3 then the other cube 6 and 5 to get 11

Reason : Both sums have one change of occuring.

A .
