1) You have a bag that contains 5 blue, 3 green, 2 red, and 1 white marble. You select a marble at random. Find each probability.

P(blue)


P(not green)

P(green or white)

P(green, then red when green is replaced)

P(red, then blue when red is not replaced)

Answer 1

See below

Explanation:

P(b) = 5/11

p(n g) = 8/11

p(g or w) = 3/11 + 1/11 = 4/11

p(g and r) = 3/11 x 2/11 = 6/121

p(r and b)= 2/11 x 5/10 = 1/11

Answer 2

P(blue): 5/11

P(not green): 8/11

P(green or white): 4/11
