Question

4 black marbles & 3 red marbles are in a bag pulling 2 marbles what is the probability of getting 2 black.?

Answer 1

4/7 x 3/6=2 in seven chance

Answer 2

Linda was closer... Sorry lea, but your probability is for pulling 1 black marble. I believe the answer is this .5714(4/7)x.2857(2/7)=.1632

Answer 3

1 in 3 chance

Answer 4

Well you have 7 marbles in all and only 4 black marbles, meaning you have 4/7 of a chance of pulling 2 black marbles out of a bag; if you want a number instead of a fraction it is 0.5714285714

Answer 5

2/7
