A bag contains 5 ​batteries, all of which are the same size and are equally likely to be selected. Each battery is a different brand. If you select 2 batteries at​ random, use the counting principle to determine how many points will be in the sample space if the batteries are selected ​a) with replacement. ​b) without replacement. ​a) With replacement

A bag contains 12 balls of the same shape and size. Of these, 9 balls are blue, and the remaining 3 balls are red. Suppose that you do the following iterative random experiment: In each iteration, 5 balls are removed randomly (without replacement) from the bag, in such a way that any 5 balls in the bag are equally likely to be the 5 balls that are removed. After doing this, you check whether among the 5 removed balls there...

A bag contains 40 jellybeans with 5 different colors. Each color is equally represented. You are interested in randomly drawing one jellybean at a time and checking the color before eating it. You want to know how many red jelly beans you will pull out of the bag during the first 10 draws. Can the probability be found by using the binomial probability formula? Why or why not? No. The trials are fixed, but the events are independent. Yes. The...

A popular flashlight that uses two D-size batteries was selected, and several of the same models were purchased to test the "continuous-use life" of D batteries. As fresh batteries were installed, each flashlight was turned on and the time noted. When the flashlight no longer produced light, the time was again noted. The resulting "life" data from Rayovac batteries had a mean of 21.8 hours. Assume these values have a normal distribution with a standard deviation of 1.38 hours. (Give...
