Question

A random survey of autos parked in student and staff lots at a large university classified the brands by country of origin, as seen in the table.

Origin	Driver
	Student	Staff
American	107	105
European	33	12
Asian	55	47

a.What is the probability that a randomly chosen driver was a student? Round to three decimals.

b.What is the probability that a randomly chosen staff member is driving a European car? Write a probability statement and round to three decimals.

c.Find the odds against the probability in part "a".

Answer 1

	Student	Staff	TOTAL
American	107	105	212
European	33	12	45
Asian	55	47	102
TOTAL	195	164	359

So, Required probability = P(randomly chosen driver was a student)

195 - 0.543 359
