Explanation / Answer
A) The probability that a randomly selected driver fatality who was male was 35 to 54years old = 14492/total number of males
= 14492/(139+5332+11015+14492+4717+3024)
= 14492/38719
= 0.374
B) The probability that a randomly selected driver fatality who was 35 to 54 was male = 14492/(14492+5056)
= 0.741
C) D. The driver is more likely to be male because the probability is greater than 0.5.
