Lincoln High School has 98 teachers. Of the 42 female teachers, 8 teach math. One seventh of all of the teachers teach math. What is the probability that a teacher is a man or does not teach math?
no of maths teachers:98/7=14
no of male maths teachers:14-8=6
no of male teachers:98-42=56
no male teachers who do not teach maths:56-6=50
