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:
3.25 can be changed to either 3 and 1/4 or 13/4.
.115 can be reduced in a fraction to 23/200
Step-by-step explanation:
So you add whats in parentheses first which gives you -11 then you end up with -11(-3)
Which will equal 33 Thats your final awnser...
33
The difference between the median of the golf pro box and tennis pro box is 20.
<h3>
What is Median?</h3>
The median is the middle value of an entire data set. If the number of data points(observations) in the set is odd then the middle value is the median but, for an even number of observations, the median is calculated by finding the means for the two middle data points.
As we know that the vertical line in the box plot is the median. Therefore, the median of the Golf pro shop is 40, while the median of the tennis pro shop is 20.
The difference between the median of the golf pro box and tennis pro box
= 40 - 20
= 20
Hence, the difference between the median of the golf pro box and tennis pro box is 20.
