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.
Answer:
The answer is: b5y + 9 = 16
Answer: 3
Step-by-step explanation:
6y (1)
2 (2)
9x (3)
Answer:
D
Step-by-step explanation:
It's not similar because when aligning the values they don't match. 3 × 5 = 15 so that bottom line matches but when you do the same thing to the other line: 5 × 3 does not equal 9. There is no similarity between the two triangles.
