Real quick, so the answer would be 1/2, 1/2, 1/2, 1/2?

OpenStudy (knov):

it's just one over 2. since it's a probability of each of your trial isa black.

Ok, I was just asking because it's multiple choice, and for each answer, there are 4 fractions

a. 1/2, 25/52, 6/13, 23/52 b. 1/2, 1/2, 1/2, 1/2 c. 1/4, 1/4, 1/4, 1/4 d. 1/2, 1/4, 1/8, 1/16
