You can solve many simple probability problems just by knowing two simple rules:

<span> The probability of any sample point can range from 0 to 1.<span> The sum of probabilities of all sample points in a sample space is equal to 1. </span></span>

The following sample problems show how to apply these rules to find (1) the probability of a sample point and (2) the probability of an event.

A circular racetrack has a diameter of 1/2 mile. How far does a car travel in one lap around the track? Round to the nearest ten
dlinn [17]
Given:
Circular racetrack with a diameter of 1/2 mile

Find: how far does a car travel in one lap around the track?

We need to find the circumference of the racetrack.

Circumference is multiplying pi to the diameter of the racetrack.

Circumference = 3.14 * 1/2 mile
Circumference = 3.14/2 mile
Circumference = 1.57 miles rounded to the nearest tenth is 1.60 miles.

Hal earns n dollars per hour. Next month he
xenn [34]

Answer:

Total = 1.02n

Step-by-step explanation:

Given

Earnings = n

Raise = 2\% --- <em>not 296</em>

Total = n + 0.02n

Required

Simplify the expression for total earning

The total amount is derived from:

Total = Earnings + Raise * Earnings

Total = n + 2\% * n

Express percentage as decimal

Total = n + 0.02 * n

Now, we can solve further:

Total = n + 0.02n

Total = 1.02n

<em>Hence, the simplified expression is 1.02n</em>
