With a mean of λ , the probability mass distribution (pmf) is given by
for λ = 4, and k<2 (i.e. k=0 or 1)
P(k<2, λ )=P(k=1, λ ) + P(k=1, λ )
=0.01832+0.07326
=0.09158 (to the fifth place of decimal)
Note: Poisson processes have no memory, so 2 calls in first hour has the same probability as 2 calls in any other hour.
Answer:
4
Step-by-step explanation:
1. Find the Mean
(8+12+15+17+18)/5=14
2.For each number, subtract the Mean and square the result.
(8-14)^2=36
(12-14)^2=4
(15-14)^2=1
(17-14)^2=9
(18-14)^2=16
3. Find the Mean of those squared differences.
(36+4+1+9+16)/5=13.2
4.Take the square root of that and this is what you want.
square root of 12.7 = 3.6 (round up to 4)
You would just do 1÷5 so it would equal 20 or 20%.
Hello There!
The answer you have selected, (D) is correct!
To get the answer you simply add the two fractions together. and 9 + 4 = 13.
13/10 is also called an irrational fraction, the more you know~
Have a great day, and maybe brainliest?
