When dealing with the number of occurrences of an event over a specified interval of time or space and when the occurrence or nonoccurrence in any interval is independent of the occurrence or nonoccurrence in any other interval, the appropriate probability distribution is a .
(a) binomial distribution.
(b) hyper geometric probability distribution.
(c) normal distribution.
(d) poisson distribution.

(D) Poisson distribution.

Step-by-step explanation:

When dealing with the number of occurrences of an event over a specified interval of time or space and when the occurrence or non occurrence in any interval is independent of the occurrence or non occurrence in any other interval, the appropriate probability distribution is a _ Poisson distribution.

This distribution is used to calculate the probability of different number of success based on the mean number of success.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
