Afood truck sells tacos, burrito, and drinks. let event a = a customer buys a taco let event b = a customer buys a drink what does p(a or b) = 0.60 mean in terms of this problem? a) the probability that a customer buys both a taco and a drink is 60%. b) buying a taco and buying s drink are mutually exclusive events. c) the probability that a customer buys either a taco or a drink is 60%. d) the probability that a customer buys neither a taco nor a drink is 60%.

Option C is correct.

Step-by-step explanation:

P(A or B) represents  that event A has occurred or event B has occurred or both events A and B are happening.

We are given P(A or B) = 0.60 or 0.60/100 = 60%

So, Option C The probability that a customer buys either a taco or a drink is 60% is correct.

Option C

Step-by-step explanation:

For two events A and B, P(A or B) represents the probability that event A occurs, or event B occurs.

In this case, event A represents a customer buys a taco and event B represents a customer buys a drink. We know that

So this means that the probability that a customer buys either a taco or a drink is 60%

The answer is the option C

Create formulas for length and perimeter.

L = 4/W
10 = 2*L + 2*W

Substitute formula for length for the length in perimeter formula
10 = 2*4/W + 2*W
10 = 8/W + 2*W
5 = 4/W + W
5W = 4 + W^2
0 = 4 - 5W + W^2
W^2 -5W + 4 = 0
You now have a standard quadratic equation with A=1, B=-5, and C=4
Using the quadratic formula you get two possible answers
W = 1, or W = 4
Let's check them
Width = 1, L = 4/1 = 4  
Width = 4, L = 4/4 = 1
Both make the same 1x4 rectangle. And the perimeter is 2*1 + 2*4 = 2+8 = 10
