The probability that a randomly selected driver fatality who was male was 55 to 69 years old is approximately I. (Round to three decimal places as needed.)

Answer 1

CI	Males	Females	prob_males	prob_females
Under 16	258	126	0.007235	0.008584
16-20	5225	2366	0.146519	0.161194
21-34	12016	4704	0.336951	0.32048
35-54	10191	4593	0.285774	0.312917
55-69	4591	1631	0.12874	0.111119
70 and over	3380	1258	0.094781	0.085706
Total	35661	14678	1	1

Driving Fatalities 14000 12000 10000 8000 LLLL 6000 4000 2000 0 Under 16 16-20 21-34 35-54 55-69 70 and over Males Females

For all,

Driving Fatalities 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 Under 16 16-20 21-34 35-54 55-69 70 and over prob_males prob_females

So, P(males in 55-69) = 4591/33661 = 0.12874 = 0.129 = 0.13

Please rate my answer and comment for doubt.
