Suppose that X and Y are jointly continuous random variables with joint density fpx, yq # yexy 0 x 8, 1 y 2 0 otherwise (a) Given that X ¡ 1, what is the expected value of Y ? (b) Given that X ¡ Y , what is the expected value of X? For this part, you are only required to set up the requisite integrals, but not required to evaluate them. (c) Compute ErX | Y s.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
