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
