Answer:
True.
Step-by-step explanation:
We are given that two disjoint sets
We have to find that the statement number of outcomes of disjoint set is equal to sum of number of outcomes for each event
If sets are disjoint then
Let n(A)=x
n(B)=y
We know that
Hence, to find the number of outcomes of disjoints set ,add the number of outcomes for each event.
Therefore, the statement is true.
The answer is A i hope this helps
The answer is B because because 12x12=144 and 13x13=169 and nothing can multiply it’s self to become 156
Answer:
Step-by-step explanation:
GIVEN: The mathematics department of a college has male professors, female professors, male teaching assistants, and female teaching assistants.
TO FIND: If a person is selected at random from the group, find the probability that the selected person is a professor or a male.
SOLUTION:
Total employees in mathematics department
Total males in mathematics department
Probability that selected person is a male
Total professor (male+female)
Probability that selected person is professor
Total male professor
Probability that selected person is a male professor
Probability that selected person is a professor or a male
Hence probability that selected person is a professor or a male is
