Question
Every weekday morning, an average of 5 people get a drink at Starbucks between 8 and 8:10am.
a) Using the Poissonprobability formula, calculate the probability of no customers getting a drink at Starbucks
between 8 and 8:10am on a randomly selected weekday morning. Use your answer to determine the
probability of at least one customer getting a drink at Starbucks between 8 and 8:10am on a randomly
selected weekday morning.
b) Determine the probability of at least ten customers getting a drink at Starbucks between 8 and
8:10am on a randomly selected weekday morning.
