Question

Motor Vehicle Accidents During a recent year, there were 13.4 million automobile accidents, 6.2 million truck accidents, and 176,000 motorcycle accidents.Find the following probabilities. Enter your answers as fractions or decimals rounded to 3 decimal places.

Answer 1

Part 1

step 1

The probability that is a truck accident is

P=6.2/(13.4+6.2+0.176)

P=0.314

step 2

The probability that is a motorcycle accident is

P=0.176/(13.4+6.2+0.176)

P=0.09

therefore

The probability that is a truck accident or a motorcycle accident is

P=0.314+0.09

P=0.404

part 2

we have that

The probability that is a truck accident is

P=6.2/(13.4+6.2+0.176)

P=0.314

therefore

the probability that not a truck accident is

P=1-0.314

P=0.686
