      So the probability of at least one person standing up is 0.6321. 6. Probability Problem--Card-Matching. This is the same problem as No. 5. P(each pair not matching) = 51/52 = 0.9808. By the extended multiplicative rule, the probability of no pairs matching is 0.9808 to the 52 power, or 0.3643. So the probability of at least one match is 0.6357. 7.

      It will be 1 - 0.80 = 0.20. d. The probability that Alex will pass exactly one course is the probability that Alex will pass only algebra or Alex will pass only history. Since these two things are mutually exclusive (the probability that Alex will pass both is 0), then we just need to add the probabilities together to get 0.55 + 0.25 = 0.80.

      The probability of a sample point is a number between 0 and 1 that measures the likelihood that this outcome will occur when the experiment is performed. Often we take this to mean the proportion of times the outcome would occur if we repeated the experiment many times. Note: (1) All sample point probabilities must be between 0 and 1.

      The At Least Once Rule (For Independent Events) Suppose the probability of an event A occurring in one trial is P(A). If all trials are independent, the probability that event A occurs at least once in n trials is. P(at least one event A in n trials)= 1 – P(no events A in n trials) = 1 – [P(not A in one trial)]n.
