Q.1 Which of the following events E and F are mutually exclusive enents ? A. When two dice are tossed E = getting a difference of 2 F = getting two even numbers Not exclusive Consider P(E)=8/36 P(F)=9/36 P(EF)=4/36 not equal to P(E)P(F) B. When a card is drawn from a pack of 52 playing-cards(withou t jokers) E = drawing a diamond F = Drawing a king not exclusive P(E)=13/52 P(F)=1/4 not equal to P(E)P(F) P(EF)=1/52 C. When a boy is chosen from class S5A E = choosing a boy with glasses F = choosing a boy with short hair Not exclusive Since if there are only one boy with glasses and short hair, then if you know this boy wear glasses, then the probability of a boy with short hair is 1 So it is not exclusive D. When a coin is tossed E = getting a head F = getting a tail Yes P(E)=P(F)=1/2 P(EF)=1/4=P(E)P(F) There are 4 married couples in a room. If a man and a woman are selected at random, what is the probability of selceting a married couple ? PROBABILITY =4/8C2 =4/28 =1/7 2008-02-15 20:03:39 補充： 第二題看錯了因為指明抽一男一女PROBABILITY=4/(4C1)(4C1)=4/16=1/4THE ANSWER IS C
