Two number cubes with faces numbered 1 to 6 are rolled. what is the probability that that sum of the rolls is 8.
a. 1/12
b. 1/11
c. 1/9
d. 5/36
e. 1/6

D

Step-by-step explanation:

Firstly, we need to know the number of total possible results. We can do this by placing the first die in horizontal band and the second die in vertical band.

The total number of results would be 36 results.

Now, to get the number of 8s

The possible sums that can give 8 is 2 and 6, 2and 5 and 3 with 4 and 4.

All are possible two times asides the 4 and 4 that could only show one time.

This means as we can have 2 and 6 we can also have 6 and 2

The total number of expected results is thus: 5/36

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

they would have to work 32 hours.
