Estimate the probability of the event.
-A polling firm, hired to estimate the likelihood of the passage of an up-coming referendum, obtained the set of survey responses to make its estimate. The encoding system for the data is: 0 = FOR, 1 = AGAINST. If the
Referendum were held today, estimate the probability that it would pass. $$0,1,1,0,0,1,0,1,1,0,0,0,1,0,1,0,0,0,1,0$$
A) 0.6
B) 0.65
C) 0.5
D) 0.4

The probability of the event is the number of favorable outcomes divided by the total number of possible outcomes. In this case, the favorable outcomes are the number of responses that are "FOR" (0), and the total number of possible outcomes is the total number of responses. There are 10 responses that are "FOR" and 10 responses that are "AGAINST", so the probability of the event is 10/20 = 0.6.
