Answer:
.56
Explanation:
The probability of a certain event always adds up to 1. Like if you are flipping a coin, 1/2 chance tails + 1/2 chance heads = 1. The coin can't do anything else than tails and heads.
In this case, either Ricky or Nicky is absolutely guaranteed to win the game.
So the probability Nicky wins is
1 - .44 = .56
