Answer: a. x=4 b. x=17.5
Step-by-step explanation:
a. 5x/2+1=11
subtract 1 from both sides : 5x/2=10
multiply both sides by 2 : 5x=20
divide both sides by 4 : x=4
b. 2x/7-3=2
add 3 to both sides : 2x/7=5
multiply both sides by 7 : 2x=35
divide both sides by 2 : x=17.5
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
<h3>Hello There !! </h3>
<h3><u>Explanation :- </u></h3>
• Amount received by Rui = 5x = 5 x 11 = $55..
• Amount received by Vishal = 9x = 9 x 11 = $99..
Let the amount received by Rui be 5x..
Then the amount received by Vishal is 9x ..
And by this data = 5x + 44 = 9x ..
• Amount received by Rui = 5x = 5 x 11 = $55..
• Amount received by Vishal = 9x = 9 x 11 = $99..
<h3>Hope this helps you..! </h3>
