Suppose you pick a marble from the bag that contains six blue marbles and nine red marbles. you record the color, put the first marble back, and then you draw a second marble. what is the probability that both marbles drawn are red? a. 1/7 b. 12/35 c. 11/29 d. 17/29 e. 27/70

Step-by-step explanation:

Given : The bag that contains six blue marbles and nine red marbles.

Number of red marbles = 9

Total marbles = 6+9=15

Total outcomes : The number of combinations of drawing 2 balls from 15 :-

Favorable outcomes : The number of combinations of drawing 2 red balls from 9 :-

Now, the probability that both marbles drawn are red :

[divided numerator and denominator by 3]

hence, the required probability =

the image of (6, 9) under a dilation is (4, 6). the scale factor is
