A bag contains 5 green marbles, 8 red marbles, 11 orange marbles, 7 brown marbles, and 12 blue marbles. You choose a marble, replace it, and choose again. What is P(red, then blue)?

Question

20/43
40/43
20/1849
96/1849
I think its B

Answer 1

p red = 9/41
replace so independent
p blue = 10/41

9/41 * 10/41 = 90/1681

Answer 2

if you replaced it your events are independent
8/43 * 12/43 = 96/1849

Answer 3

Thx Damon

Answer 4

You are welcome.

Answer 5

P(red) = 8/43

P(blue) = 12/43

multiply the two probabilities (independent events)
