Rework problem 17 from section 2.1 of your text, involving the outcomes of
an experiment. For this problem, assume that outcome O 1 has frequency 12/a, outcome O 2 has frequency 5/a, and outcome O 3 has frequency 3/a. There are only 3 outcomes. I tried to substitute a variable and got 5 but that was wrong. I am really unsure of how to get the right answer here, any tips to get me in the right direction?

can be solved only if the outcomes are mutually exclusive (non- overlapping) & exhaustive (probabilities adding up to 1)
12/a + 5/a + 3/a = 1 , 20/a = 1,
a = 20
