Answer 1

Answer:

1. There is 1/9th chance that you'll get a multiple of 3 twice.

2. There is 2/3rds chance that you'll get a black ball.

Step-by-step explanation:

There is 1/3 chance that when you roll a dice once, you'll get a multiple of 3, so when you roll twice, there will be a (1/3)*(1/3) chance that you will get a multiple of 3 twice. (1/3)*(1/3)=1/9, so therefore, there is 1/9th chance that you will roll a multiple of 3 twice.

For every 1 white ball, there are 2 black balls. The ratio for black balls to white balls is 2:1. That means that there is 2/3rds chance that you will get a black ball.
