Answer:
64
Step-by-step explanation:
The probability that of the questions studied, all three were the test questions selected by the professor is 0.05.
<h3>How to find the probability?</h3>
We can find the probability by dividing the total number of favorable events by the total number of events.
The total number of events is given by
.
The total number of favorable events is given by
.
The probability is given by = Favorable events/Total number of events
= 
= 
= 
= 0.05
The probability that all three questions are selected by the professor for the test is found to be 0.05.
Therefore, we have found that the probability that of the questions studied, all three were the test questions selected by the professor is 0.05.
