You can put this solution on YOUR website! 1/In a recent poll by the american automobile club 40% of the surveyed said that they were worried about aggressive drivers. If 3 people are randomly selected, what is the probability that all 3 will be worried about aggressive driveres::: (0.40)^3 = 0.0640
--------------------------------------
2/ a container has 5 blue marbles, 3 red marbles, and 6 white marbles. If 3 marbles are drawn with replacement, what is the probability that all three will be blue? ::: 5C3/14C3 = 0.0275
--------------------------------------
3/ In how many ways can the letters in "chapter" be arranged
Ans: 7! = 5040
--------------------------------------
4/ two dice are rolled. Find the probability of getting a sum of 6
::: 5/36
--------------------------------------
5/ A password of 3 letters must be selected. If the letters may be repeated, how many 3 letter password will be possible:::26^3 = 17576
