# Common Core: 7th Grade Math : Finding Experimental Probability

## Example Questions

### Example Question #1 : Finding Experimental Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. What is the experimental probability of the spinner landing on the pink section?

Explanation:

The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinner  times, and she landed on pink  times; thus, our experimental probability is

### Example Question #2 : Finding Experimental Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. What is the experimental probability of the spinner landing on the orange section?

Explanation:

The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinner  times, and she landed on orange  times; thus, our experimental probability is

### Example Question #3 : Finding Experimental Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. What is the experimental probability of the spinner landing on the yellow section?

Explanation:

The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinner  times, and she landed on yellow  times; thus, our experimental probability is

### Example Question #191 : Statistics & Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. What is the experimental probability of the spinner landing on the green section?

Explanation:

The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinner  times, and she landed on green  times; thus, our experimental probability is

### Example Question #5 : Finding Experimental Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. Is the experimental probability of landing on yellow more likely, less likely, or equally likely in comparison to the theoretical probability?

Results can't be found based on the data provided

More likely

Equally likely

Less likely

Less likely

Explanation:

The theoretical probability is what should happen. In this case, we have  spaces and  of those spaces is yellow; thus, the theoretical probability of the spinner landing on yellow should always be  or

The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinner  times, and she landed on yellow  times; thus, our experimental probability is

In order to compare the theoretical probability and the experimental probability let's convert the fractions into decimals so we can put them on a number line:

A probability closer to  means that an event is more likely to occur. In this case,  is closer to ; thus, the experimental probability is less likely than the theoretical probability.

### Example Question #6 : Finding Experimental Probability

Kelly spun a spinner, which is pictured below,  times. She recorded her results in the table provided. Is the experimental probability of landing on green more likely, less likely, or equally likely in comparison to the theoretical probability?

More likely

Less likely

Results can't be found based on the data provided

Equally likely
