Answer:
a) 4/9
b) 2/3
hope it helps!
Step-by-step explanation:
a) number is yellow m&ms = 20
total number of m&ms = 10+15+20
= 45
Probability of getting a yellow m&m = 20/45
= 4/9
b) Number of blue m&ms = 15
Number of m&ms that aren't blue = 45-15 = 30
Total number of m&ms = 45
Probability of getting something besides blue m&m = 30/45
= 2/3
