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
