A boy puts 50 marbles in a jar in which 16 are red, 14 are blue, and 20 are yellow. If he
picks one marble at random, what is the probability that he selects a red marble or yellow
marble?​

Sagot :

Use a franction formula:

50/16= 3 is the probability that he selects a red marble.


50/20= 2 is the probability that he selects a yellow marble.

3+2= 5 is the probability that he selects a red marble or yellow marble.

Hope makatulong sayo;)
