  5. 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.
