Giving a test to a group of students, the grades and gender are summarized below
A B C Total
Male 12 8 3 23
Female 19 18 4 41
Total 31 26 7 64

If one student is chosen at random, find the probability that the student earned grade B given the student is female. Round your answer to four decimal places.
Giving a test to a group of students, the table below summarizes the grade earned by gender.

If one student is chosen at random, find the probability that the student was not a female and did not earn grade C. Round your answer to four decimal places.
Well, if the student was not a male, that means they were either a female or a toaster. But since the probability of a toaster being in the group is pretty low, we can assume they were a female.
Now, let's look at the number of females who got an "A". From the table, we can see that there were 19 females who got an "A", out of a total of 64 students.
Therefore, the probability that the student was NOT a male that got an "A" is 19/64.
Remember, learning is fun, even when it involves probability and gender!
To find the probability that the student was NOT a male that got an "A", we need to find the number of students that meet this criteria and divide it by the total number of students.
From the given information, we can see that the number of males who got an "A" is 12.
To find the number of students that were NOT a male and got an "A", we need to calculate the total number of students who got an "A" and then subtract the number of males who got an "A".
The total number of students who got an "A" is the sum of the males who got an "A" (12) and the females who got an "A" (19).
Total number of students who got an "A" = 12 + 19 = 31
Now, to find the probability, we divide the number of NOT male students who got an "A" by the total number of students:
Probability = Number of NOT male students who got an "A" / Total number of students
Number of NOT male students who got an "A" = Total number of students who got an "A" - Number of males who got an "A"
= 31 - 12
= 19
Total number of students = Total number of males + Total number of females
= 23 + 41
= 64
Now we can calculate the probability:
Probability = Number of NOT male students who got an "A" / Total number of students
= 19 / 64
= 0.296875
Therefore, the probability that the student chosen at random was NOT a male that got an "A" is approximately 0.296875 or 29.69%.
Twelve students were males who got an A. Therefore there were 52 students who were not males who got an A.
52/64 = 13/16
