Answer:
a. 0.69
b. 0.13

Step-by-step explanation:
Total number = 100
a) either means students with either option are valid
69/100 = 0.69
b) both means each student has done both math and english
=13/100 = 0.13
c) Only one means has done one subject and not both classes. We have 23 for math and 33 for english (this is according to your venn diagram)
23+33=56
one subject =56/100 = 0.56

Answer:
option b
Step-by-step explanation:
root 129
Brand X costs $1.56 for 12 ounces
Brand X: cost of each ounce = $1.56 / 12 = $0.13
Brand Y costs 2 cents more per ounce, so the cost of brand Y per ounce= $0.13 + $0.02 = $0.15
The cost of 15 ounces of brand Y = $0.15 x 15 = $2.25
Answer
$2.25
