When you multiply terms with like bases you add the exponents together. The base stays the same. When you divide terms with like bases you subtract the exponent of the denominator from the exponent of the numerator. This is called getting the power of a power.
Answer:
t =5
Step-by-step explanation:
-7(2-t)=21
-14+7t=21

We can't tell from the information given. What we do know is
P(A ∩ B) = P(A|B) P(B)
We're given the conditional probability but not the probability of the conjunction.
If we were told P(A|B)=0.8 and P(A ∩ B)=0.12 we could conclude
P(B)=P(A ∩ B)/P(A|B) = 0.12/0.8 = 0.15
but that wasn't the problem asked.
