3. Camille rolls two number cubes together
and records the sum. If she does this
180 times, how many times should she
expect the sum to be 7? Explain your answer

30 times she should expect he sum to be 7.

Step-by-step explanation:

Here we have , Camille rolls two number cubes together  and records the sum. If she does this  180 times, We need to find how many times should she  expect the sum to be 7 . Let's find out:

Total number of outcomes are 36 ( there can be 36 pairs of sum possible ) , and favorable outcomes are :

i.e. 6 , So

Probability = ( Favorable outcomes )/( Total outcomes )

⇒

But , she does this  180 times so we have ,

⇒

⇒

Therefore , 30 times she should expect he sum to be 7.
