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.
SA = 2(1/2)(3)(4) + 3(5.5) + 4(5.5) + 5(5.5)
SA = 12 + 16.5 + 22 + 27.5 = 78
D. since 11% in decimal is 0.11 only. 1/9 in decimal is 0.111111111... 0.12 jorge and 1/8 in decimal is 0.125
The first thing you need to know is that an absolute value graph looks like a 'v' shape.
Then you need to find the y intercept.
In this case the y-intercept would be at the point (0,5).
Since it is just a y = |x| graph with no coefficients in front of the x. On the right of point (0,5) the graph is increasing with a slope of 1 as in the picture. On the left of the point (0,5) it is a linear line which has a slope of -1. Your final graph should look like a v shape, and look like the graph I drew in the picture attached.
