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?
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on pinktimes; 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?
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on orangetimes; thus, our experimental probability is
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 yellow section?
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on yellowtimes; thus, our experimental probability is
Example Question #4 :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 green section?
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on greentimes; 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. 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
Equally likely
More likely
less likely
less likely
The theoretical probability is what should happen. In this case, we havespaces andof those spaces is yellow; thus, the theoretical probability of the spinner landing on yellow should always beor
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on yellowtimes; 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 tomeans 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?
Results can't be found based on the data provided
More likely
less likely
Equally likely
less likely
The theoretical probability is what should happen. In this case, we havespaces andof those spaces is green; thus, the theoretical probability of the spinner landing on green should always be
The experimental probability is what actually happened in an experiment. In this case, Kelly spun the spinnertimes, and she landed on greentimes; 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 tomeans 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.
