The success rate of the Fana soccer team depends on a number of factors. The fitness of the players is one of the factors that influence the outcome of a match.
+ The probability that all the players are fit for the next match is 70%
+ If all the players are fit to play the next match, the probability of winning the match is 55%.
+ If there are players that are not fit to play the next match, the probability of winning the match is 55%.
Based on fitness alone, calculate the probability that the Fana soccer team will win the next match.
