Juan says that the probability of picking two white marbles without replacing from a bag containing 3 solid white marbles and 5 striped marbles is equal to 1/64 is juan correct explain. A-juan is correct the probability of drawing any marble is 1/8 and 1/8 Γ—1/8=1/64
B-juan is incorrect the probability of drawing a white marble is 3/8 and 3/8Γ—3/8=9/64
C-juan is incorrect since one of the marbles is taken after the first draw 3/8Γ—2/8=6/64=3/32
