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.
