Answer:
Correct option is B
Step-by-step explanation:
Generally the respond dependent variable can be defined as a variable whose values are dependent on the changes in other variable
Now in this question the respond (dependent) variable is the cost of meal , this because from the question the interest of Zagat is to predict the cost of a meal from the Zagat service rating
So in this case the independent variable is Zagat service rating
While the responds dependent variable is cost of meal
We need to find the probability of the event:
having blue eyes or blond hair
This event is the union of the events:
A: having blue eyes.
B: having blond hair.
So, we need to find the probability P(A ∪ B). In order to do so, we can use the following formula:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
We know that the probability of the intersection of A and B (having both) is
P(A ∩ B) = 24%
Also:
P(A) = 43%
P(B) = 46%
Then, using those values into the above formula, we find:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
P(A ∪ B) = 43% + 46% - 24%
P(A ∪ B) = (43 + 46 - 24)%
P(A ∪ B) = 65%
