73.33% probability that they also took the SAT
Step-by-step explanation:
We have these following two events.
Event A: Taking the ACT exam. So P(A) = 0.3.
Event B: Taking the SAT exam. So P(B) = 0.37.
The conditional probability formula is:
In which P(B|A) is the probability of event B happening given that A has happened, is the probability of both events hapenning.
22% of graduating seniors too both exams.
This means that
If the student took the ACT, what is the probability that they also took the SAT?

2. True, all even numbers are multiple of 2, and thus divisible by 2. Any number that is divisible by 2 must be a multiple of 2. hence,the given biconditional statement in true.
3. True, all multiples of 5 has 0 or 5 in the ones place.
Thus the given biconditional statement is true.
