Answers
Step-by-step explanation
Given : A card is drawn at random from a pack of 52 cards.
To Find : the probability that it will be a card of heart or club or seven
Solution:
pack of 52 cards.
=> n(S) = 52
E = a card of heart or club or seven
13 Cards of Heart
13 club
4 Seven
1 Seven of Club ( counted twice in club as well in 7)
1 Seven of Heart ( counted twice in Heart as well in 7)
n(E) = 13 + 13 + 4 - 1 - 1
=> n(E) = 28
P(E) = n(E)/n(S) = 28/52 = 7/13
the probability that it will be a card of heart or club or seven = 7/13
