Answer:
3/20
Explanation:
Given:
Probability that it is Monday and that a student is absent is 3/100
Probability that a randomly selected day of the school week is monday is 1/5
To Find:
What is the probability that a student is absent given that today is Monday.
Solve:
It may be different if it were on a Wednesday. Because we expect fewer absentees on Wednesday than on Monday/ Friday. In these cases the conditional probability, P(absent/weekday) would differ depending on the day of the week.
3/100 ÷ 1/5 = 3/20
The probability that a student is absent on a Monday is 3/20
