प्रश्न
A handbag contained fifty ten rupees note, thirty-five fifty rupees note and fifteen hundred rupee note. One note is drawn from a handbag. What is the probability of getting:
Ten rupees note
उत्तर
Total number of notes = 50 + 35 + 15 = 100
Let E1 represent the event in which the chosen note is a 10 rupee note.
The number of ten rupee notes is 50.
Thus, P(E1) = `"Number of ten rupees note"/"Total number of notes"`
= `50/100`
= `1/2`

If one die is rolled, then find the probability of the following event by completing the activity.
Event A: The number on the upper face is prime.
Activity: Let ‘S’ be the sample space.
S = {1, 2, 3, 4, 5, 6}
∴ n(S) = 6
Event A: Prime number on the upper face.
A = {`square`}
∴ n(A) = 3
P(A) = `square/(n(S))` .....[Formula]
= `square/6`
∴ P(A) = `1/square`

An urn contains 12 red balls, 15 yellow balls and 18 blue balls. A ball is choosen at random, then to find the probability of choosing a blue and red coloured balls, fill in the boxes.
Total number of balls = 12 + `square` + `square` = `square`
(1) Let E be the event that the choosen ball is blue.
Number of blue balls = `square`
Thus,
P(E) = `"Number of blue balls"/"Total number of balls"`
= `square/square`
(2) Let F be the event that the choosen ball is red.
Number of red balls = `square`
Thus,
P(F) = `square/"Total number of balls"`
= `square/square`
