Question

In a bag there are 4 black marbles and 2 green marbles. What is the probability of choosing a black marble, not replacing it, then choosing a green marble?

Answer 1

It'd be 4/15

Explanation:

The total marbles is 6, so for black it's 4/6, but it's not being put back in so for the next one, the denominator would be 5. For green it's 2/5

4/6 times 2/5 equal 4/15

Hope this helps!
