# Ajar contains five red marbles and three green marbles. a marble is drawn at random and not

replaced. a second marble is then drawn from the jar. find the probability that the first marble is red and the second marble is green.

Answer from: kevin1015wangoudf1t

The jar starts out with 8 marbles in it. Five of them are red.

If you don't peek, the probability of drawing a red marble is

5/8 .

If you have already drawn a red marble on the first try, then

at that point, the jar has only 7 marbles in it, and three of them

are green. Now, for your second draw, if you don't peek, the

probability of drawing a green marble is

3/7 .

The probability of BOTH of those events being successful is

(5/8) x (3/7) = 15/56 = approx 26.79% .

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
