In order to figure out conditional probability you look at a select group from a larger group. If there are 245,600 people and 113,500 are Women. 20,534 male prefer chocolate chip cookies versus 15,937 male prefer oatmeal cookies. What is the conditional probability that a
male who prefers chocolate chip cookies will be chosen. Show your work!!!

Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs.

Example: the probability that a card drawn is red (p(red) = 0.5).

Another example: the probability that a card drawn is a 4 (p(four)=1/13).

Joint probability: p(A and B). The probability of event A and event B occurring.

look a the sides they are perpendicular

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
