Probability of getting a republican voter is
These are found by dividing the first numerator and denominator by 2, then by 3
To make it complete, the situation is therefore defined as where y is unknown value
(b)
Cross multiplication of the probability and number of voters gives the actual figure of y in the equation formed in part a of the question.
(c)
Since we have 15240 voters who plan to participate in election, we cross multiply to get the approximate number of republican voters which yields
