Question

Cards each marked with one of the number 4,5,6.....20 are placed in a box and mixed thoroughly.One card is drawn at random from the box .Find the probability of getting an even prime number

Answer 1

Answer:

Step-by-step explanation:

Total outcomes=20-4+1=17.

Favourable outcomes (even primes)=1

Probability=1/17

Answer 2

Your answer is

Sample space =S={4,5,6,......,29

n (S) ={17}

Let A be the event of getting an even prime number

A ={2}

Therefore n (A) = {1}

Therefore P (A) = n (A)/n (S)= 1/17

Therefore the probability of getting an even prime numbers is 1/17

I hope that this will help you
