A test was given to a group of students. The grades and gender are summarized below:
A B C Total
Male 14 9 18 41
Female 7 13 12 32
Total 21 22 30 73
(a) If one student is chosen at random from those who took the test, Find the probability that the student got a 'A' GIVEN they are female.

The probability that the student got a 'A' and is female is 9,59%

Step-by-step explanation:

To get the probability  equally likely of choosing a specific student, we use the following formula

P=# of possibilities that meet the condition / #of equally likely possibilities.

# of possibilities that meet the condition= 7

#of equally likely possibilities= 73

P(fem grade A)= 7/73= 0,0959=9,59%

she drove 134 miles

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
