Using the Fundamental Counting Theorem and the probability concept, it is found that:
- There are
ways to answer all 17 questions.
probability you will get them all right.
<h3>What is the Fundamental Counting Theorem?</h3>
- It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:
<h3>What is a probability?</h3>
- A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
- The questions in part A and in part B are independent.
- For the 12 questions in part A, there are
ways to answer, hence 
.
- For the 5 questions in part B, there are
ways to answer, hence 
.
Then:
There are ways to answer all 17 questions.
Only one outcome in which all the guesses are correct, hence:
probability you will get them all right.

Answer:
B
Step-by-step explanation:
Since Pink Chips are 9, that means you should start would 9/18 and multiply that by 8 since 1 would be the same number. then, you have your answer
490=10·40+15x
490=400+15x
90=15x
x=6
he worked a total of 46 hours
Answer:
