A large proportion of small businesses in the United States fail during the first few years of operation. On average, 1.6 businesses file for bankruptcy per day in a particular large city.

Round your answers to four decimal places.

a. Using the Poisson formula, find the probability that exactly 2 businesses will file for bankruptcy on a given day in this city.

P( exactly 2)= Enter you answer; P(exactly 2)

b. Using the Poisson probabilities table, find the probability that during a given week the number of businesses that will file for bankruptcy on a given day in this city is

i. 2 to 3

P( 2 to 3)= Enter you answer; P(2 to 3)

ii. more than 3

P(more than 3)= Enter you answer; P(more than 3)

iii. less than 3

P(less than 3)= Enter you answer; P(less than 3)
