The following table shows the number of cars that have been serviced by the last month. age and type during Domestic Import 12 0 to under 5 years old 5 to under 10 vears old 10 to under 15 years okd 15 Given that a randomly selected car from this sample was an import, the probablity that the car was from 10 to under 15 years old is 0 to under 15 years old is 0.253 0.311 0.416 0.500 QUESTION 3 Two six-sided die are rolled. The probability of the sum of the two die being a 10 is 0.056 0.083 e 0.139

I need 2 and 3

Answer 1

Given that a randomly selected car from this sample was an import, the probability that the car was from 10 to 15 years old

$= \frac{15}{ 6 + 9 +15} = \frac{15}{30} = 0.5$

3. Two six sided die are rolled.

Total number of sample points = 6² = 36

To get a sum of 10, the favorable sample points are { (4,6),(6,4),(5,5)}

The probability of the sum being a 10 is

$= \frac{3}{36} = 0.083333$

ans-> 0.083
