    Q1. A firm rents cars from three agencies, 20% from agency X, 35% fromagency Y, and 45% from agency Z. 70% of the cars rented from agency X,85% of the cars rented from agency Y, and 95% of the cars rented agencyZ are black. If a car is randomly selected from the firm, find thefollowing probabilities and give your answers correct to 4 decimalplaces.

i) The selected car is black.
0.7*0.2+0.35*0.85+0.95*0.45=
0.865

ii) The selected car is rented from agency Y given that the selected car is black.
(0.85*0.45)/0.865

Q2. A carton contains 11 rechargeable batteries, one of which isdefective. How many ways can three rechargeable batteries be chosen if

i) one of them is defective?

10C2*1C1

ii)none of them is defective?
10C3


Q3. A team of five is randomly chosen from six girls and seven boys.How many different ways can the team be chosen if there must be moregirls than boys in the team.

if all points lie on the line y=a+bx, then can i say that all points also lie on the line x=c+dy??

    if all points lie on the line y=a+bx, then can i say that all points also lie on the line x=c+dy??

x=c+dy
y= -c/d+x/d

so , only if a=-c/d , b=d
then all points lie on the line y=a+bx also lie on the line x=c+dy


其实你要问什么topic的

correlation and regression
