If you simply solve the equation for w, rather than "guess and check" using the values in the "replacement set," you find ...
... 6w +6 = 60 . . . . simplify the equation
... 6w = 54 . . . . . . . subtract 6
... w = 9 . . . . . . . . . divide by 6
The appropriate choice is ...
... D. 9
-15,-5,-2,1,3,8 it's pretty simple
Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2. Let's repeat the experiment of Example 1, with a die instead of a coin.
