Answer:
Step-by-step explanation:
The nth term of an AP is
where, a is the first term of the sequence and d is common difference.
The given linear sequence is
22 , 18 , 14 , 10 , 6 , . . .
Here, first term is 22 and common difference is
The common difference of the sequence is -4. So, the nth term of given sequence is
Therefore, the nth term of the sequence is .

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.
