Answer:
Taylor = 50%
Moore = 25%
Jenkins = 25%
Step-by-step explanation:
Assuming there are no other candidates and that someone has to win the election, the probabilities of Taylor, Moore, and Jenkins winning the election must add up to 1 or 100%.

Since Moore and Jenkins have about the same probability of winning, and Taylor is believed to be twice as likely to win as either of the others:

Taylor has a probability of 50% of winning the election.
Moore has a probability of 25% of winning the election.
Jenkins has a probability of 25% of winning the election.
