(4.1.4) Let X and Y be Bernoulli random variables. Let Z = X + Y. a. Show that if X and Y cannot both be equal to 1, then Z is a
Fynjy0 [20]

Step-by-step explanation:

Given that,

a)

X ~ Bernoulli (p_x) and Y ~ Bernoulli (y_x)

X + Y = Z

The possible value for Z are Z = 0 when X = 0 and Y = 0

and Z = 1 when X = 0 and Y = 1 or when X = 1 and Y = 0

If X and Y can not be both equal to 1 , then the probability mass function of the random variable Z takes on the value of 0 for any value of Z other than 0 and 1,

Therefore Z is a Bernoulli random variable

b)

If X and Y can not be both equal to  1

then,

p_z = P(X=1 or Y=1)\\

p_z = P(X=1)+P(Y=1)-P(=1 and Y =1)

p_z = P(x=1)+P(Y=1)\\\\p_z=p_x+p_y

c)

If both X = 1 and Y = 1 then Z = 2

The possible values of the random variable Z are 0, 1 and 2.

since a  Bernoulli variable should be take on only values 0 and 1 the random variable Z does not have Bernoulli distribution

Many people enjoy challenging themselves by running in marathons. A marathon is a 26-mile race. The runners wear numbers that id
Rudiy27
First we clear y from the given equation
 x + 10y = 260
 10y = 260-x
 y = (260-x) / (10)
 Then, we evaluate the function within the domain of it
 x = 0
 y = (260- (0)) / (10)
 y = (260) / (10)
 y = 26
 x = 10
 y = (260- (10)) / (10)
 y = (250) / (10)
 y = 25
 That is, you travel 1 mile in 10 minutes.
 Therefore, traveling 26 miles will take:
 (26) * (10) = 260 min
 answer
 it takes for the runner to reach the school 260min.

3/5 + 4/15 = in simply
maksim [4K]
You have to get a common denominator so

3 x 3 = 9
5 x 3 = 15

So now we have 9/15 + 4/15 which is 13/15.

The answer is 13/15

N0 If n=143 what is the answer a b or c
den301095 [7]

Answer:

C

Step-by-step explanation:

Well, anything multiplied by zero is zero.

If you multiplied 0 by 143, you wouldn't get anything because you're not multiplying with another number that can be multiplied by.
