To determine the probability of the spinner landing on a 3, we need to find the number of favorable outcomes (which in this case is landing on a 3) and divide it by the total number of possible outcomes on the spinner.
In this case, the spinner has 6 equal sections. Only one section is labeled with a 3.
So,
Number of favorable outcomes = 1
Total number of possible outcomes = 6
Therefore, the probability of the spinner landing on a 3 is:
Simplified fraction: 1/6
Decimal: 0.1667 (rounded to four decimal places)
Percent: 16.67%
The theoretical probability of a simple event is P(event) = number of favorable outcomestotal number of outcomes in a sample space
EXAMPLE: A jar contains 10 green, 7 red, and 3 blue marbles. What is the probability of randomly picking a red marble?
P(red) = number of red marblestotal number of marbles in the sample space=710+7+3=720
The probability of randomly picking a red marble is
720=0.35=35%
