The given MGF is that for a random variable following a Poisson distribution with parameter
.
This means
, and
has PMF
So, the desired probability is
This is equivalent to
The result of dividing
by
is
with no remainder. Please check the step by step procedures in the picture attached.
We can conclude that:
The quotient of the division is
The remainder of the division is
The divisor is
The dividend is
Well costheta=1, at 0, 2pi,...
knowing this we can exclude the first two as the are not undefined anywhere.
tan is sin/cos, at 0 sin is also 0 so it becomes 0/1 which is 0, not undefined.
sec is1/cos, cos is 1, this is just 1
csc is 1/sin, sin is 0, 1/0 is undefined, meaning there will be an asymptote
cot is cos/sin, this is again 1/0, so it is also an asymptote
The last two answers are the ones you want
Answer:
2
Step-by-step explanation:
4-5= -1
13-18+2= (-5+2)= -3
-1-(-3)=2
Don't forget your order of operations
P (parenthesis)
E (exponents)
MD (multiplication/division)
AS (addition/subtraction)
