Ten cards numbere

Answer :

Ten cards are numbered, hence the sample space is


S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, n(S) = 10


Let event A be the even number card drawn, then


A = {2, 4, 6, 8, 10}, n(A)=5


Now probability that an even card is drawn is



Let event B be the cards greater than 3, then


B = {4, 5, 6, 7, 8, 9, 10}, n(B) = 7



So the probability of AB


So, AB = {4, 6, 8, 10}, n(AB)=4



So the required probability will become



Hence the probability that an even card is drawn out of cards that are more than 3 is
