A bag contains 40 marbles, 4 of which are blue, 10 are red, 25 are green, and 1 is purple. Shawna takes a marble out of the bag, records the color, and returns it to the bag. How many green marbles should she expect after 400 trials?

Best ResponseYou've already chosen the best response.1the experimental frequency to get a green marble is: 25/40= 5/8 so the requested number is: \[\Large \frac{5}{8} \cdot 400 = ...?\]

Best ResponseYou've already chosen the best response.1hint: \[\Large \frac{5}{8} \cdot 400 = \frac{{5 \cdot 400}}{8} = ...?\]

Best ResponseYou've already chosen the best response.1here the experimental probability, is given by the subsequent ration: favorable outcomes/total outcomes: \[\Large \frac{{272}}{{600}} = ...?\]

Best ResponseYou've already chosen the best response.1whereas the theoretical probability is: favorable outcomes (= 3, since there are three odd numbers) / possible outcomes(=6, since there are six possible outcomes): \[\Large \frac{3}{6} = ...?\]

Best ResponseYou've already chosen the best response.1we have: 272/600=0.453 and 3/6=0.5 so what can you conclude?

Best ResponseYou've already chosen the best response.1we can see that experimental probability is less than the relative frequency
