Answer:
a. 1/2
b. 1/2
c. 5/6
d. 1/6
Step-by-step explanation:
Here, we are going to base the probability of the next tests on what we have presently
we have 6 scores to work with
a. more than 70%
Scores above 70 are 3
So the probability will be 3/6 = 1/2
b. less than 70%
Scores below 70 are 3
So the probability will be 3/6 = 1/2
c. At least 60%
This means that 60 or more
scores here are 5
So the probability is 5/6
d. 80% marks
we have only 1 80%
so the probability is 1/6
