Using the probability concept, it is found that there is a:
a) 0.3014 = 30.14% probability that the driver is male and 19 or under.
b) 0.592 = 59.2% probability that the driver is age 20 or female.
c) 0.4118 = 41.18% probability that the driver is at least 20 years old.
A probability is the number of desired outcomes divided by the number of outcomes.
Item a:
- In total, there are 4746 + 4517 + 1625 + 1553 + 1679 + 1627 = 15747 drivers.
- Of those, 4746 are male and 19 or under, hence:
[tex]p = \frac{4746}{15747} = 0.3014[/tex]
There is a 0.3014 = 30.14% probability that the driver is male and 19 or under.
Item b:
- 4517 + 1553 + 1627 = 7697 are female, and 1625 are males aged 20, hence:
[tex]p = \frac{7697 + 1625}{15747} = 0.592[/tex]
0.592 = 59.2% probability that the driver is age 20 or female.
Item c:
- 1625 + 1553 + 1679 + 1627 = 6484 are at least 20, hence:
[tex]p = \frac{6484}{15747} = 0.4118[/tex]
0.4118 = 41.18% probability that the driver is at least 20 years old.
