At a car and truck dealership the probability that a vehicle is white is 0.25 the probability that it is a pickup truck is 0.15 the probability that it is a white pickup truck is 0.06 what is the probability that a vehicle is white given that the vehicle is a pick up truck round your answer to two decimal points

Step-by-step

Given:

W=vehicle is White

T=vehicle is a pick-up Truck

P(W and T)=0.06

P(W)=0.25

P(T)=0.15

We need the conditional probability that a vehicle is white, given that it is a pick-up truck:

P(W | T)

= P(W and T) / P(T)

= 0.06 / 0.15

=0.4

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
