Hello, I hope you can help me with the following question. I appreciate it greatly.

Thank you!

The question:

Example

a) On this example we will examine the probability a couple who has 8 children has exactly 5 boys.

b) Next we will look at the probability that they have more than 5 boys.

c) Finally we will look at the probability that they have at most 5 boys.

Assume a .5 chance of having a boy.

Solution can be solved using excel.

a) On this example we will examine the probability a couple who has 8 children has exactly 5 boys.

Type this in an excel cell

=binom.dist(5,8,.5,False)

and then hit enter

.21875 would be the answer

b) Next we will look at the probability that they have more than 5 boys.

Type this in an excel cell

=1-binom.dist(5,8,.5,True)

and then hit enter

.144531 would be the answer

c) Finally we will look at the probability that they have at most 5 boys.

Assume a .5 chance of having a boy.

Type thisin an excel cell

=binom.dist(5,8,.5,True)

and hit enter

.855469 would be the answer

My question now using the foregoing scenario:

A teacher has a total of 10 students of both girls and boys.

A.) find the probability of the teachers students were exactly 4 girls.

mya

b.) Find the probability of the teacher will not have less than 4 girls.

C.) Find the probability of the teachers will have at the most 4 girls.

Can you provide an excel document example of the answer as well?

Thank you so much!
