A die is thrown once. Find the probability of getting.

(a) a prime number.

(b) an odd number

###### Advertisements

#### Solution

Total outcomes of throwing a dice once are 1, 2, 3, 4, 5 and 6**(1) Probability of getting a prime number**

Prime numbers are 2, 3 and 5 in throwing a die once

Probability of getting a prime number = `3/6 = 1/2`

**(2) Probability of getting an odd number**

odd numbers are those that are not divisible by 2.

So, there three odd numbers in throwing a dice once which is 1, 3 and 5.

Probability of getting an odd number = `3/6 = 1/2`

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`
