Find a probability. A bag contains 10 red M&Ms, 15 blue M&Ms, and 20 yellow M&Ms. a) What is the probability of drawing a yellow M&M? b) What is the probability of drawing something besides a blue M&M?

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

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
