he theoretical probability of a simple event is P(event) = number of favorable outcomes total 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% Use the spinner below to complete the problem. Determine the probability of the spinner landing on a 3.(3 points)Enter the probability as a SIMPLIFIED fraction: Enter the probability as a decimal with two decimal places: Enter the probability as a percent: %Skip to navigation PreviousNext
The spinner has 8 equal sections, and only 1 of those sections is labeled as "3".
So, the probability of the spinner landing on a 3 is:
- Simplified fraction: 1/8
- Decimal: 0.125
- Percent: 12.5%
