A quiz has five true or false questions. How many possible ways could the five questions be answered?
1 answer:
Answer:
The total number of ways to answer = 32
Step-by-step explanation:
A quiz has five questions that can be answered as true or false.
Each question can be answered in two ways.
Lets take each question one by one.
The first question can be answered as true or false that is two ways.
Similarly each question answered in 2 ways.
To get the total number of ways, we have to multiply the number of ways for each question.
Hence the total number of questions =
= 32

Step-by-step explanation:
Given
i.e. first to fifth
Required
Determine number of selection
1st position = Any of the 30 students
2nd position = Any of the 29 students
3rd position = Any of the 28 students
4th position = Any of the 27 students
5th position = Any of the 26 students
Number of selection is then calculated as:
Answer:
p(on schedule) ≈ 0.7755
Step-by-step explanation:
A suitable probability calculator can show you this answer.
_____
The z-values corresponding to the build time limits are ...
z = (37.5 -45)/6.75 ≈ -1.1111
z = (54 -45)/6.75 ≈ 1.3333
You can look these up in a suitable CDF table and find the difference between the values you find. That will be about ...
0.90879 -0.13326 = 0.77553
The probability assembly will stay on schedule is about 78%.
