Question

A die is thrown once. What is the probability of getting a number greater than 4?
 

Sum

Solution

A dice is thrown once

TO FIND: Probability of getting a number greater than 4

Total number on a dice is 6.

Numbers greater than 4 are 5 and 6

Total number of numbers greater than 4 is 2

`"We know that PROBABILITY"=" Number of favourable event"/"Total number of event"` 

`"Hence probability of getting a number greater than 4 is equal to" =2/6=1/3`

`"Hence probability of getting a number greater than 4 is "1/3`

A card is drawn at random from a pack of well shuffled 52 playing cards. Complete the following activity to find the probability that the card drawn is:

Event A: The card drawn is an ace.

Event B: The card drawn is a spade.

Activity: 'S' is the sample space.

∴ n(S) = 52

Event A: The card drawn is an ace.

∴ n(A) = `square`

P(A) = `square`  ......(formula)

∴ P(A) = `square/52`

∴ P(A) = `square/13`

Event B: The card drawn is a spade.

∴ n(B) = `square`

P(B) = `(n(B))/(n(S))`

∴ P(B) = `square/4`
