There are 4 white marbles out of 8 total marbles.
That's 4/8 or 1/2 chance you would draw a white.
1/2 or 50%.

The chances of the first marble being red are 4 in 10 (or 2 in 5). 4 red marbles, 10 marbles total. If the first marble is replaced, the chances of the second being red is the same, giving you a probability of both being red of: 2/5 x 2/5 = 4/25 If the first marble isn't replaced before the second is pulled out, the chances are 3 in 9 (1 in 3), giving you a probability that both are red of: 2/5 x 1/3 = 2/15

4 / (3 + 1 + 4) = 4/8 = 1/2.

3 black+1 striped+ 4 white =8 total.
Your answer would be 4/8 or 50/50 or 1/2 or 50%
