One card is drawn from a pack of 52 cards, each of the 52 cards being equally likely to be drawn. Find the probability that the card is drawn is either red or king.
उत्तर
n(S) = 52
Event = {either red or king}
Event = { 26 red cards + 2 kings }
Event = 28
n(E) = 28
P(E) = ?
∴ P(E) = `"n(E)"/"n(S)" = 28/52 = 7/13`
