Answer:
{r,z}
Step-by-step explanation:
U = {r,s,t,u,v,w,x,y,z}
P = {s,t,u,v,w}
Q = {u,v,x,y}
P' means elements in the universe,U, that are not in P.
P'={r,x,y,z}.
Q' means elements in the universe,U, that are not in Q.
Q'={r,s,t,w,z}.
P' intersect Q' means what elements are in common in both lists.
{r,z}

Answer:
(-6, 4)
Step-by-step explanation:
Given the coordinate points (-3,1). If The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction the required coordinate will be expressed ss;
X' = (-3-3, 1+3)
X = (-6, 4)
Hence the resulting coordinate will be at:(-6, 4)
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.
![P(X=x) = e^{-6.4} * [6.4^{x} / x!] when x = 0, 1, ...](https://tex.z-dn.net/?f=P%28X%3Dx%29%20%3D%20e%5E%7B-6.4%7D%20%2A%20%5B6.4%5E%7Bx%7D%20%2F%20x%21%5D%20when%20x%20%3D%200%2C%201%2C%20...)
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
