Wheres the picture or the problem????

Answer: D
Step-by-step explanation:
Sketch and label the sampling distribution for the sample proportion of games containing a big bang, according to the Central Limit Theorem, assuming that the grandfather's null hypothesis is true. Also check whether or not the conditions hold for the CLT to apply. Of the 95 games in our sample, 47 contained a big bang.
Assume the secret number is x.
"Al doubled the number and added 15 to the result. He got 51."
means 2x+15=51
solving for x:
2x+15=51
2x=51-15
2x=36
x=18
"Beverly did the same operations with their number, but in the reversed order." means she first added 15 to the number, then she doubled the result,
that is she performed the operation:
First: x+15
then: 2(x+15)
since we found x=18, then we have 2(x+15)=2(18+15)=2*33=66
Answer: 66
