Therefore, ( ) F P F S Students are advised to find the probability in case of (iii), (iv) and (v). PROBABILITY Example Find the probability that when a hand of cards is drawn from a well shuffled deck of cards, it contains (i) all Kings (ii) Kings (iii) atleast Kings. Solution Total number of possible hands = C (i) Number of hands with Kings = C C × (other cards must be chosen from the rest cards) Hence P (a hand will have Kings) = C C C × Number of hands with Kings and non-King cards = C C × Therefore P ( Kings) = C C C × (iii) P(atleast King) = P( Kings or Kings) = P( Kings) + P( Kings) Example If A, B, C are three events associated with a random experiment, prove that P A B C ∪ ∪
