459. A card is selected from a pack of 52 cards. Calculate the probability that the card is (i) an ace (ii) black card.


One card is drawn from a deck of 52 cards.
rightwards double arrow Number of points in the sample space S = n(S) = straight C presuperscript 52 subscript 1 equals 52.
Event A = the card is an ace (one out of 4 aces)
rightwards double arrow                n(A) = straight C presuperscript 4 subscript 1
Hence,   straight P left parenthesis straight A right parenthesis space equals space fraction numerator straight C presuperscript 4 subscript 1 over denominator straight C presuperscript 52 subscript 1 end fraction equals 4 over 52 equals 1 over 13
Hence, the probability of getting an ace = 1 over 13
Event B: the card drawn is a black card.               (one out of 26 black cards)
rightwards double arrow        n(B) = straight C presuperscript 26 subscript 1
rightwards double arrow         space space straight P left parenthesis straight B right parenthesis space equals space fraction numerator straight n left parenthesis straight B right parenthesis over denominator straight n left parenthesis straight S right parenthesis end fraction equals fraction numerator straight C presuperscript 26 subscript 1 over denominator straight C presuperscript 52 subscript 1 end fraction equals 26 over 52 equals 1 half
