A certain university has 15 vehicles available for use by faculty and staff. Five of these are vans and 10 are cars. On a particular day, only two requests for vehicles have been made. Suppose that the two vehicles to be assigned are chosen in a completely random fashion from among the

a. Let E denote the event that the first vehicle assigned is a van. What is P(E) ?
b. Let F denote the probability that the second vehicle assigned is a van. What is P(F | E)?
c. Use the results of parts(a) and (b) to calculate P(E and F)

no

explanation:

you can be freinds, and people but not follow people.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
