Answer:
The probability that there will be a total of 7 defects on four units is 0.14.
Step-by-step explanation:
A Poisson distribution describes the probability distribution of number of success in a specified time interval.
The probability distribution function for a Poisson distribution is:

Let <em>X</em> = number of defects in a unit produced.
It is provided that there are, on average, 2 defects per unit produced.
Then in 4 units the number of defects is,
.
Compute the probability of exactly 7 defects in 4 units as follows:

Thus, the probability of exactly 7 defects in 4 units is 0.14.

It is irrational because you cant write it as a fraction
Answer:
For the shape you must do 3*3*3 + 2*2*2 + 1 unit cubed, or 36 units^3
For Jessy's jewelry box, you must multiply the side lengths, 3*10*3, or 90 inches^3
