2 green marbles_____? 2 red marbles_______? A black and green marble_____? A green and a red marble______?

Answer 1

Answer:

The answers are as follows:

2 Green = 25%

2 Red = 4%

1 Black 1 Green = 15%

1 Green 1 Red = 10%

Step-by-step explanation:

In order to find any of these, we first have to find the probability of pulling any of them individually. To find that, we simply divide the number of marbles by the total in the jar.

Green = 5/10 = 50%

Black = 3/10 = 30%

Red = 2/10 = 20%

Now to find any combination, simply multiply the percentages together. For instance, for 1 black and 1 green, multiply those percentages together.

Black * Green

30% * 50% = 15%

You can do this for any number of combinations
