Answer : D

The denominators are same
So we combine the numerators

To remove parenthesis we distribute negative sign inside the second parenthesis



Morgan made a mistake. He forgot to distribute the negative sign
Morgan forgot to distribute the negative sign to two of the terms 2t and 2 inside second parenthesis
Answer:
The probability of the number of starfish dropping below 3 is 0.0463.
Step-by-step explanation:
Let X represent the number of starfish in the tide pool.
X follows a Poisson distribution with mean 6.4.
The formula for Poisson distribution is as follows.
otherwise
We need to find the probability that the number of starfish in the tide pool drops below 3.
Therefore, the required probability is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X=2)
P(X < 3) = 0.00166 + 0.01063 + 0.03403
P (X < 3) = 0.0463
X = 7
5 + x can also be written as 5 + 7
5 + 7 = 12
Put the first number on top then start adding 6+0, 8+1, 0+4, 1+1, 0+0 and the answer is 69420
Multiply the fraction by both things in the parenthesis.
