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%.
