Answer:
5/8
Step-by-step explanation:
Find P(x = 3 blues for the 2 draws)
two draws
Binomial probability.
we know p = 3/8 for blue, else q = 1 - q = 1 - (3/8)
X = # of blue marbles left in the bag.
apparently it looks like there are 8 marbles in the bag, 3 are blue, 5 are red
X = 3 , means the draw was a red 5/8 for the first draw
the 2nd draw can be a blue or a red so, probability is 1
P(X = 3) = (5/8) * 1 = 5/8
1/3x+3x. Hope that helps! :D
