Peter does a lot of commuting by cycle.  Occasionally he gets a puncture while out riding (and very occasionally two).  Peter wants to determine the expected value for the number of punctures on a ride, so that he can determine how many puncture repair patches he should purchase to get him through 100 rides. Let x be the number of punctures on a given ride. The probability of getting one puncture is p(1) = 0.08 The probability of getting two punctures is p(2) = 0.01 The probability of getting zero punctures is 1 - p(1)-p(2) Find the expected value for the number of punctures for a given ride and multiply this by 100 and then round to the nearest integer to determine how many patches Peter should purchase.  Type your answer below.简答题
