Complete parts (a) through (c) below. a. If two different employees are randomly selected, what is the probability that they were both hired on the first business day of the month? The probability is Type an integer or a simplified fraction.)Explanation / Answer
4.4.22. a) P(both were hired on first business day) = 1/20 x 1/20
= 1/400
4.4.23. P(both involved intoxicated driver) = [(22+29)/171] x [50/170]
= 0.088
The event is not unlikely
4.4.25. Number of intoxicated drivers = 18+30 = 48
P(all 3 deaths involved intoxicated drivers) = 48/125 x 47/124 x 46/123
= 0.054433
4.4.27. P(did not make obscene gesture) = (2670-280)/2670
= 0.8951
4.4.29. a) Number of good tires = 6700 - 270 = 6430
P(all tyres are good) = 6430C4/6700C4
= 0.848
b) P(100 good tires) = 6430C100/6700C100
= 0.016
Yes, this outlet must plan to deal with defective tires
