Answer:
A
Step-by-step explanation:
This is an example of conditional probability because we are trying to find the probability of an event occurring GIVEN the occurrence of some other event. There is a formula for this (see image attached).
If we follow this formula, the numerator would be the probability of (A AND B) which in this case is "48% of the class passed BOTH exams." The denominator in the formula would be that "60% of the class passed ONLY THE SECOND exam."
Therefore, P(A and B) = 0.48, which is 48% expressed as a decimal and P(B)= 0.60, which is 60% expressed as a decimal. Then, you can figure out the answer by dividing.
To solve this, you need to do 1,266-451. that equals 815. then, divide 815 by 19. you should get 43. hope that helps.
Ur answer is 17 dollars cause u add 14 to 69 and u get 83 then you subtract 83 from 100 which equals 17
The answer would be 84.6
You multiply 94 and 90 and then add a decimal point since you can’t go over 90.
That’s how I do it mentally.
