Answer:
60%
Step-by-step explanation:
first do 28+32.

Answer:
P(Y=1|X=3)=0.125
Step-by-step explanation:
Given :
p(1,1)=0
p(2,1)=0.1
p(3,1)=0.05
p(1,2)=0.05
p(2,2)=0.3
p(3,2)=0.1
p(1,3)=0.05
p(2,3)=0.1
p(3,3)=0.25
Now we are supposed to find the conditional mass function of Y given X=3 : P(Y=1|X=3)
P(X=3) = P(X=3,Y=1)+P(X=3,Y=2) +P(X=3,Y=3)
P(X=3)=p(3,1) +p(3,2) +p(3,3)
P(X=3)=0.05+0.1+0.25=0.4

Hence P(Y=1|X=3)=0.125
Answer:
Question #1 It is three dollars of so the cost is $12
Question #2 The answer is 6
Question #3 21.25
Step-by-step explanation:
It's a number that can be expressed as a fraction, the numerator and the denominator of which, are integers.
The answer if i’m not wrong would be r 3-2 equals 1 which is r.
