One card is randomly drawn from a pack of 52 cards. Find the probability that: the drawn card is red or king.
उत्तर
In randomly drawing a card from 52 cards.
n(S) = 52
Let D denote the event that the drawn card is red or a king.
n(D) = 26 (red cards ) + 2(kings)
n(D) = 28
P(D) = `"n(D)"/"n(S)" = 28/52 = 7/13`
