Best answer 2 votes 2 votes Question is basically asking what is the probability of other 2 items being red (so that all 5 are red). So sample space = {(red, red), (red, not red), (not red, red), (not red, not red)} P(all 5 are red) = 1/4 Option (3) rfzahid answered Dec 11, 2017 • selected Dec 30, 2017 by atul_21 rfzahid comment Share Follow See all 0 reply Please log in or register to add a comment.
