Question

[PLEASE HELP BEEN STUCK ON UT FOR HOURS :(] There are three colors of marbles in the bag: red, green, and yellow. If the probability of getting a red was 2/5 and the probability of getting a green was 1/3, what is the probability (in fraction form) of getting yellow?

Answer 1

= 5 /11

Explanation:

Probability here is the chance of selection out of a total. So, we need to first find the total number of marbles.

P green = 3 /11

P yellow = 2 /11

P green or yellow

= P green + P yellow

= 3 /11 + 2 /11 = 5 /11
