18. use the spinner to find each theoretical probability
a. p (an even number)
b. p (a number greater than 3)
c. p (an odd number)

In the spinner there are eight numbers numbered from 1 to 8. To solve this problem, we must remember that probability is:

Probability = number of successful events / number of total events

a. P (even number). There are 4 even numbers, therefore the probability is:

P (even number) = 4 / 8

P (even number) = ½ = 0.5 = 50%

The probability of getting an even number is 50%.

b. P (a number greater than 3). There are 5 numbers greater than 3, therefore the probability is:

P (number greater than 3) = 5 / 8

P (number greater than 3) = 0.625 = 62.50%

The probability of getting a number greater than 3 is 50%.

c. P (an odd number). Similar to the even number, there are 4 odd numbers. Therefore,

The probability of getting an odd number is 50%.

slope is 35 and 20 miles is the y-intercept.
