Question

Find the probability:
A bag contains 4 red marbles, 16 yellow marbles, 5 purple marbles, 16 blue marbles, and 10 green marbles. What is the probability of pulling out a red or a green marble?

Answer 1

P(red) = 4/51
P(green) = 10/51
The event red or green can happen in 2 different and mutually exclusive ways. So the probability of it happening is the sum of the separate probabilities.
Can you now solve it?

Answer 2

Would that be 14/51?

Answer 3

Good work! You've got it :)

Answer 4

That's the answer?

Answer 5

Yes
