Concept explainers
a.
The probability that the selected point is the mid-point.
The probability that the selected point is the mid-point is
Given: One of the five labelled point is selected.
Concept used: Here, we are using formula of probability which is
Calculation: Here, the formula is
Favorable outcomes = 2 and Total outcomes = 5
By putting the values in the given formula, we get
→
Conclusion: Hence, the probability that the selected point is the mid-point is
b.
Probability that both the selected points are mid-points.
Probability that both the selected points are mid-points is
Given: Two of the five points are randomly chosen.
Concept used: Here, we are using formula of probability which is
Calculation: Here, the formula is
Favorable outcomes = 1 and total outcomes = 10 putting these values in the given formula
→
Conclusion: Hence, Probability that both the selected points are mid-points is
