Suppose you have a bag that contains 2 black and 8 striped marbles. You select one marble, replace it, and then select another. Find the probability that you will select two black marbles in a row. P(black & black) =

2/10 (1/5)

Step-by-step explanation:

to do this, you know that the marble is put back, so you have an equal chance each time. then, find how many black marbles there are, and go from there.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
