Fifty dash two percent of people in a certain country like to cook and 54% of people in the country like to shop, while 28% enjoy both activities. What is the probability that a randomly selected person in the country enjoys cooking or shopping or both? The probability that a randomly selected person in the country enjoys cooking or shopping or both is

78%

Step-by-step explanation:

Given the information, we can write:

P(cook) = 52%

P(shop) = 54%

P(cook and shop) = 28%

Now, we need to find P(cook or shop).

We need probability formula for general addition rule, which is:

P(A or B) = P(A) + P(B) - P(A and B)

We can take "cooking" and Event "A" and "shopping" as Event "B".

Thus, we write:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.52 + 0.54 - 0.28

P(A or B) = 0.78

Which is 78%

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

what i would say the best answer is a. 40.5
