Question

If a card is drawn at random from the cards numbered 10 to 20, then the probability of getting a prime number is ____

Answer 1

Answer:

4/11

Step-by-step explanation:

there are 4 prime numbers between 10 and 20 i.e. 11,13,17 and 19=4

there are 11 numbers from 10 to 20=11

the probability = no of favorable outcomes/ total number of outcomes

therefore 4/11

hence answer =4/11
