Document Summary
What is the probability that the next three babies are of the same gender? (a) 0 (b) 1/2 (c) 1/3 (d) 1/4 (e) 1/8. Solution: p (bbb) + p (ggg) = 2/8 = 1/4: suppose that a university determines the following distribution for the number of courses taken by full-time students, where k is some constant. What is the probability that a randomly selected full-time student takes no more than four courses? (a) 0. 40 (b) 0. 14 (c) 0. 30 (d) 0. 70 (e) 0. 25. Solution: let x be number of courses that full-time students take. P (x 4) = 1 p (x > 4) = 0. 7: the probability that a visit to a primary care physician"s (pcp) o ce results in neither lab work nor referral to a specialist is 35%. Of those coming to a pcp"s o ce, 30% are referred to specialists and 40% require lab work.
