Experimental vs. Theoretical Probability

Learn experimental vs. theoretical probability! Practice sorting and calculating with fun examples.

Experimental vs. Theoretical Probability Watch the 3-minute video about experimental and theoretical probability to answer the questions!! theoretical probability the probability of an event happening based on the the possible outcomes ("what should happen") experimental probability the ratio of the number of times an event occurs to the total number of trials ("what actually happens") Sort each scenario into experimental vs. theoretical probability categories! Theoretical Probability The probability of me rolling a 4 on a regular, 6-sided dice is 1 The probability of flipping a coin and having it land on tails is 1 A spinner has four equal sections. The likelihood of landing on one of the sections is 1 Experimental Probability I flipped a coin 50 times and 23 times it landed on heads. a 6-sided dice is rolled 20 times and it landed on a 5, 7 times. A spinner with four equal sections is spun 100 times Choose the word that goes in each blank based on the definitions of experimental and theoretical probabiity. Theoretical probability calculates the number of times an event can happen, while experimental probability calculates the number of times an event actually did happen. Choose the word that goes in each blank based on the definitions of experimental and theoretical probabiity. Theoretical probability uses only knowledge, while experimental probability uses actual experience. A spinner with four equal sections is spun 100 times. The results are listed in the table below. What is the THEORETICAL probability of spinning red? 19 1 31 3 The same spinner from the previous problem with four equal sections is spun 100 times. The results are listed in the table below. What is the EXPERIMENTAL probability of spinning red? 1 31 19 2 You roll a die ten times. Three of those times, you get a 6. What is the experimental probability of rolling a 6? 3 1 1 1 You flip a coin 50 times and get 20 tails. What is the experimental probability of getting tails? 1 10 20 30 Look at the spinner below. All of the 6 sections are equal size! What is the theoretical probability of landing on orange? 1 1 1 1 You spin the spinner 20 times and it lands on orange 5 times. What is your experimental probability of landing on orange? 1 5 or 1 3 1
