The Turtles are playing the Lizards. If the probability that the Turtles win the football game is 0.65, and the probability that the Lizards win is 0.2, find the probability of this.
P(There is a tie)
please please explain as you're solving, this problem really frustrates me. Thank you

Logically, there are only three possibilities: either the Turtles win, or the Lizards win, or they Tie. These possibilities are mutually exclusive and collectively exhaustive, so:
1 = P(Turtles win) + P(Lizards win) + P(tie)
Therefore:
P(tie) = 1 - P(Turtles win) - P(Lizards win) = 1-.65-.2 = .15

So, if the chance that the turtles will win is 65%, and the probability the turtles will lose is 20%, then the probability of a tie is:
100%- (65%+20%) = 15% or .15
