Abag contains 5 blue marbles and 8 orange marbles. polly draws a marble from the bag and then replaces it back into the bag. perry then draws a marble from the bag. what is the probability that both polly and perry draw an orange marble from the bag? which expression will find the answer? a) 8/13 x 7/12 b) 13/8 x 13/8 c) 13/8 x 12/7 d) 8/13 x 8/13

Given there are 5 blue marbles and 8 orange marbles.

Total number of marbles in the bag =5+8=13.

Probability of Polly drawing an orange marble =

As the marbles are replaced .

Probability of Perry drawing an orange marble =

The probability that both Polly and Perry draw an orange marble from the bag =

Option D is the right answer.

x + 4/7

step-by-step explanation:

use cymath

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
