Answer:

Step-by-step explanation:

P(a or b) = P(a) + P(b) - P(a and b)

0.88 = 0.70 + 0.60 - P(a and b)

P(a and b) = 1.30 - 0.88 = 0.42.

So the events a and b are not mutually exclusive.

The price of a microwave oven went up from $75 to $90; then went on sale for $57. What is the percent decrease from the original

Arisa [49]

Answer:

The percent decrease of the microwave from the original price to the sale price is 24%

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Original price of a microwave = $ 75

Mark-up price of the microwave = $ 90

Sale price of the microwave = $ 57

2. What is the percent decrease from the original price to the sale price?

For answering this question we will use the Direct Rule of Three this way:

Price Percentage

75 100%

57 x

75x = 57 * 100

75x = 5,700

x = 5,700/75

x = 76

76 = 100 - 24

The percent decrease of the microwave from the original price to the sale price is 24%
