I'll mark brainliest! a bag contains 7 blue marbles, 8 green marbles, 15 red marbles, and 10 yellow marbles. find the probability of randomly drawing without replacement, a blue marble and then a red. a. 7/160 or about 0.0438 b. 21/320 or about 0.0656 c. 7/104 or about 0.0673 d. 15/66 or about 0.2273

The correct answer option is c. 7/104 or about 0.0673.

Step-by-step explanation:

We are given that a bag has 7 blue marbles, 8 green marbles, 15 red marbles, and 10 yellow marbles.

We are to find the probability of randomly drawing without replacement, a blue marble and then a red.

P (blue) =

P (red | blue) =

P (blue then a red) = × = 7/104 or 0.0673
