Question

Can someone plz correct me ?

Answer 1

I believe you have the correct answer

Explanation:

The probability of drawing a black marble from bag 1 is 2/3.

The probability of drawing a black marble from bag 2 is 1/4.

Since it is consecutive draws, we would multiply the 2 odds.

2/3 * 1/4 = 1/6

There may be a problem with the software you're using if it is marked incorrectly.

Answer 2

They are wording it tricky, but it is simple. So first if you combine all the balls together there are 7, and 3 blacks ball 3/7.
