The probability of a customer arrival at a grocery service counter in any one second is equal to 0.4. Assume that customers arrive in a random stream, so an arrival in any one second is independent of all others. (Round your answers to four decimal places.) (a) Find the probability that the first arrival will occur during the fourth one-second interval. 0.0864 (b) Find the probability that the first arrival will not occur until at least the fourth one-second interval.

The probability of a customer arrival at a grocery service counter in any one second is equal to. $1 .$ Assume that customers arrive in a random stream and hence that an arrival in any one second is independent of all others. Find the probability that the first arrival a. will occur during the third one-second interval. b. will not occur until at least the third one-second interval.
Discrete Random Variables and Their Probability Distributions
The Geometric Probability Distribution
A grocery store counts the number of customers who arrive during an hour. The average over a year is 29 customers per hour. Assume the arrival of customers follows a Poisson distribution. (It usually does.) Find the probability that at least one customer arrives in a particular one minute period. Round your answer to 3 decimals. 0.3833 Find the probability that at least two customers arrive in a particular 4 minute period. Round your answer to four decimals.
