Answer:
Correct option: fourth one -> 87.6% (it is missing the point between 7 and 6)
Step-by-step explanation:
We have a total of 872 customers surveyed, and from this total, 384 were male, so the number of female is 872 - 384 = 488
From the 488 female, we know that 171 females prefer the Buffalo pizza, so the number of females that prefer the bbq pizza is 488 - 171 = 317.
If 425 customers prefered the bbq pizza, we know that the number of customers that prefer the buffalo pizza is 872 - 425 = 447
To find the probability of a customer being female or prefering the buffalo pizza, we can use this formula:
N(female or buffalo) = N(female) + N(buffalo) - N(female and buffalo)
N(female or buffalo) = 488 + 447 - 171 = 764
So the probability of chosing a female or someone that prefer buffalo is:
P = N(female or buffalo) / N(total) = 764 / 872 = 87.6%
Correct option: fourth one (it is missing the point between 7 and 6)
Answer:
87.6%
Step-by-step explanation:
Given:
Sample size, n = 872
Females who preferred Buffalo chicken pizza = 171
Total number of Males = 384
The total number of females would be: 872 - 384 = 488.
To find the total number that prefers bufflo since 425 prefer BBQ, we have: 872 - 425 = 447
The probability of a customer be female or preferring bufallo would be:
Number of female or buffalo = Number of female + Number that prefers buffalo - Number of female and buffalo
= 488 + 447 - 171 = 764
To find the probability that a customer chosen at random will be a female OR prefers Buffalo, we have:
Number of female or buffalo / total number of people
Therefore, we have:
[tex]= \frac{764}{872} = 0.876[/tex]
0.876 * 100 = 87.6%
The probability that a customer chosen at random will be a female or prefers Buffalo is 87.6%
