Answer:

No. of outcome = 9

Total no. of outcome = 20

Probability of getting a prime number = no. of outcome / Total no. of outcome

                                                               = 9/20 Ans

Step-by-step explanation:

Let F be event of drawing a card with prime number from the cards with numbers 1 to 20

Prime numbers from 1 to 20=2,3,5,7,11,13,17,19

No. of favorable outcomes=8

Total no. of possible outcomes =20

We know that, Probability P(F) =

(Total no.of possible outcomes)

(No.of favorable outcomes). = 8/20 = 2/5

Therefore, the probability that a card with prime number is selected from numbers 1,2,3,...,20

= 2/ 5
