Answer:
6.875
Step-by-step explanation:
7- (1/2)^3 = 7-1/8 = 6.875
Assuming they are dice, to work out the probability that the product is 8, the dice either have to be 2 and 4 or 4 and 2. The blue dice therefore has to be a 2 (4 is not less than 3), which is a 1 in 6 probability. The yellow one therefore has to be 4, which again is 1 in 6. The probablility that these both happen at the same time is given when they are multiplied together.

First, replace

and

. Then you have

If we take

, then immediately we see a differential in the numerator in the form of

. So the integral becomes

and evaluates to

making (A) the correct answer.
