Nataliya [291]

I don't know of any algebraic way to answer this, but 59,60,61 add up to 180, and 60^3 would be the greatest product of 3 numbers, so 59,60,61 yield the greatest product.

A bag contains 6 red marbles, 3 blue marbles and 8 green marbles. If three marbles are drawn out of the bag, what is the probabi

ale4655 [162]

This is a 4 step problem.

Find the probability of drawing a green marble the first time

8 green marbles ÷ 17 total marbles

Next, we find the probability of drawing a green marble the second time

7 green marbles ÷ 16 total marbles

Find the probability of drawing a green marble the third time

6 green marbles ÷ 15 total marbles

We take away one from the total marbles and green marbles each time because we are finding the probability that we draw a green marble all three times

Last step:

Multiply all the probabilities

$\frac{8}{17}$ × $\frac{7}{16}$ × $\frac{6}{15}$
