Assume that the Poisson distribution applies. Assume that the mean number of potholes on a major highway in the city of Chicago is 10.2. Compute the probability that the number potholes over 3 miles randomly slected highway​ is:   Round answers to three decimal places. Remember the fractional rule of leading zeros.   ​(1) Exactly seven.  I'm using StatCrunch and got P(x=7)= 0.085     ​(2) Fewer than seven.   P(x<7)= 0.118   ​(3) At least seven.    Got: P[x(greater than or equal to sign)7=0.882     ​(4) Would it be unusal for a randomly selected​ 3-mile stretch of highway in Chicago to contain more than 15​ potholes?   I am picking YES...but then I saw the 3 mile thing in the original question - did I miss something?     A. ​Yes, it is unusual   B. ​No, it is not unusual
