(06.02)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.1there are 25 green marbles out of a total of 40 so the property of picking a green marble is 25/40 = 5/8

Best ResponseYou've already chosen the best response.1so the expected number in 400 tyrials is 400 * 5/8

Best ResponseYou've already chosen the best response.0(06.02)A sixsided number cube labeled 1 through 6 is rolled 500 times. An odd number is rolled 325 times. Compare the experimental probability of rolling an odd number with the theoretical probability of rolling an odd number and select one of the statements below that best describes the situation. The experimental probability and theoretical probability are the same The experimental probability is larger than the theoretical probability The experimental probability is smaller than the theoretical probability There is not enough information to determine the relative frequency

Best ResponseYou've already chosen the best response.1the experimental P of rolling odd = 325/500 = 13/20

Best ResponseYou've already chosen the best response.0what does that mean lol

Best ResponseYou've already chosen the best response.1now what do you think the theoretical probability of getting an odd number is? Note there are an equal number of odd and even numbers on the cube

Best ResponseYou've already chosen the best response.1the experimental probability is the result of experimenting  the 500 rolls of the cube.

Best ResponseYou've already chosen the best response.1no they are not the same the theoretical is what you might expect to get  due to the fact that there are an equal number of odd and even numbers

Best ResponseYou've already chosen the best response.1yes or as a fraction its 1/2  well its same for odd numbers on a dice  2 possiblities odd or even

Best ResponseYou've already chosen the best response.0can you give me the answer lol i dont get any of this

Best ResponseYou've already chosen the best response.1experimental probability = 13/20 theoretical probability = 1/2 so now you can pick the correct option

Best ResponseYou've already chosen the best response.1you understand the coin part so you should understand the cube part you have 6 numbers on a cube 135 and 246  that is 2 lots  one odd and one even so P(even) = 3/6 = 1/2 and P(odd) = 3/6 = 1/2 also
