Question

A card is drawn from cards numbered from 5 to 37. Find the probability.

(i) Number is prime (ii) divisible by 3.​

Answer 1

Step-by-step explanation:

There are total 32 numbers .

i)prime numbers =16

p=16/32

p=1/2

ii) numbers divisible by 3=11

p=11/32

p=11/32.

Answer 2

Answer:

A card is drawn from 5 to 37 numbered cards means ,

total outcomes are 33,

probability = no of possible outcomes/total outcomes

1) number is prime,

primes in between 5 to 37 are 5,7,11,13,17,19,23,29,31,37.

I.e, no of possible outcomes = 10

therefore,

probability of a card drawn is prime no = 10/33

2) divisible by 3,

Nos divisible by 3 from 5 to 37 are 6,9,12,15,18,21,24,27,30,33,36.

i.e,no of possible outcomes = 11,

therefore,

probability of a card divisible by 3 is 11/33 = 1/3
