Question

A box contains 2 red marbles, 3 white marbles, 4 green marbles, and 1

blue marble. Two marbles, one after the other, are drawn at random
WITHOUT replacement. Find the probability of: selecting a green marble
on the second draw if the first marble is blue *

1/6
2/13
4/9
1/9​

Answer 1

I think the answer is 4/9

Answer 2

Solution is 4/9

Step-by-step explanation:

A box contains:

2 red marbles,

3 white marbles,

4 green marbles,

1 blue marble.

=> Total: 2 + 3 + 4 + 1 = 10

After selected a blue one without replacement, the remaining number: 10 - 1 = 9

=> Probability of drawing a green one: P = 4/9.

Hope this helps!
