Answer:
5/29
Step-by-step explanation:
This is a compound event.
Compound events are found by multiplying the probabilities of both events.
So we need to multiply the probability of chooseing a red marble and rolling an even number.
10 red
8 green
5 blue
6 white
Total marbles = 29
P(red marble) = 10/29
A die/number cube has 6 sides. Each has a probability of 1/6.
1
2
3
4
5
6
There are 3 even numbers here. The probability of an even number is:
P(even) = 3/6 = 1/2
Now we need to find the probability of both events occurring. So multiply both probabilities and you will get the answer:
10/29 x 1/2 = 5/29
The probability of choosing a red marble and rolling an even number is 5/29.
