Answer: 1. 1/2 + try to figure out the rest I believe in you
Step-by-step explanation:
First cross simplify 1. 1/2 2/2 = 1/1 x 1/2, then multiply 1 x 1, then 1 x 2 = 1/2 for the first one, use the same for the rest.
You have a 1/1000 chance of getting the code correct
This region as the same area as the one in your previous question.
Pr[1 < <em>Z</em> < 2] = Pr[-2 < <em>Z</em> < -1] ≈ 0.14
Answer:Pois(ln(200))
Step-byy-step explanation:
Let N be the number of received calls in a day
That is
N∼Pois(λ).
0.5% = 0.5/100 = 1/200 of no calls
P(N=0)=e^−λ=1/200
-λ=e^(1/200)
λ=in(200)
Our number of calls in a day is distributed Pois(ln(200)).
