Answer 1

There are 12 marble if you add them all together, (3+2+4+3=12)

• the probability of drawing a yellow is 2/12

• the probability of drawing a red marble is 4/11

• The probability of drawing a black is 3/10

Multiply them together.

2/12 times 4/11 times 3/10.

=24/1320

Explanation:

Answer 2

There are 13 marbles all together
Probability of drawing a yellow is 2/12
Don’t replace the marble
The probability of drawing a red marble is 4/11
Don’t put the marbles back in
The probability of drawing a black is 3/10
Multiply them together.
2/12 times 4/11 times 3/10.
24/1320 or. 1/55
