Set A = integer values between 10 and 15, inclusive
A = {10,11,12,13,14,15}
There are 15-10+1 = 6 items in set A
If each item has equal probaility of being chosen, then each has probaility 1/6. Think of rolling a die. For more information, check out "discrete uniform distribution".
This is what the probaility distribution looks like in tabular form.
X | P(X) | 10 | 1/6 | 11 | 1/6 | 12 | 1/6 | 13 | 1/6 | 14 | 1/6 | 15 | 1/6 |
The bar graph will have 6 bars each of identical height 1/6.
The x axis labels will be 10,11,12,13,14,15 to represent the 6 bars.
The y axis is the probaility (the taller the bar, the more likely the event will happen).
