Answer:
The number of different ways are 22! or 1,124,000,727,777,607,680,000.
Step-by-step explanation:
Consider the provided information.
We need to determine the number of different ways can a class of 22 second graders line up.
We need to select 22 second graders while taking 22 at a time.
So use the permutation formula:
Substitute n=22 and simplify.
Hence, the number of different ways are 22! or 1,124,000,727,777,607,680,000.
Answer with Step-by-step explanation:
Let
A=Students are female
B=Students major in civil engineering
The probability that a students are female=P(A)=
The probability that a student major in civil engineering=P(B)=
The probability that students both are female=
a.We have to find the probability that a random selected female student major in civil engineering.
We have to find
Hence, the probability that a randomly selected female student majors in civil engineering=0.24
b.We have to find the probability that a random selected civil engineering major is female.
We have to find
Hence, the probability that a randomly selected civil engineering major is female=0.63
