Answer:
A
Step-by-step explanation:
Using the binomial distribution, it is found that there is a 0.7941 = 79.41% probability that at least one of them is named Joe.
For each student, there are only two possible outcomes, either they are named Joe, or they are not. The probability of a student being named Joe is independent of any other student, hence, the <em>binomial distribution</em> is used to solve this question.
<h3>Binomial probability distribution
</h3>
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- One in ten students are named Joe, hence
.
- There are 15 students in the class, hence
.
The probability that at least one of them is named Joe is:
In which:
Then:
0.7941 = 79.41% probability that at least one of them is named Joe.

Relax. Take deep breaths. Feel the fresh air flowing down to your toes.
It's only some lame math. It can't scare you, because you have a brain
and you know how to use it.
You need to find the Patriots' score. You don't know what it is yet, so
let's give it a label. I've got a brilliant idea ! Let's call it 'P' !
What do we know ?
We know that the Patriots won the game, so we know that the Giants'
score was less than 'P'.
How much less was it ? The question tells us that the difference in
their scores was 20. So the Giants scored P-20 in the game.
What else do we know ? The question tells us the sum of the scores.
OK. Let's addum up:
Patriots' score: P
Giants' score: P - 20
Sum of the scores: P + (P - 20) = 2P - 20
The question tells us that their sum was 44.
OK. 2P - 20 = 44
That's an equation. Solve it for 'P' and you'll have the answer.
Add 20 to each side: 2P = 64
Divide each side by 2: P = 32
There you are. The Patriots scored 32.
The Giants scored 20 less ... (32 - 20) = 12.
The sum of their scores was (32 + 12) = 44.
Everything checks out.
