Question

Among the licensed drivers in the same age group, what is the probability that a 78-year-old was involved in an accident? Use the table below.​

Answer 1

4.2

Explanation:

<333

Answer 2

C. 6.6%

Explanation:

The probability of an event 'A' occurring, P(A) is given by the ratio of the number of times event A occurs to the some of all possible events

Mathematically, we have;

`The \ probability \ of \ an \ event = (The \ number \ of \ the \ required \ outcome)/(The \ number \ of \ all \ possible \ outcomes)`

The number of drivers involved in an accident who are above 75 years = 13,321

The total number of drivers in accidents = (10,034 + 17,173+ 35,712+ 40,322 + 40,937 + 30,355 + 17,246 + 13,321) = 205,100

A 78-year-old is in the age group of 75 and older

∴ The probability that a 78-year-old licensed driver was involved in an accident = The probability that a 75 and older year-old licensed driver was involved in an accident = 13,321/205,100 ≈ 0.06495 = 6.5%

Therefore, the best option is option C. 6.6%
