A teacher is chosen at random. The probability that the teacher is female is 3/5. There are 36 male teachers. How many teachers in total work at the school?
Info given = probability that the teacher is female = 3/5 36 male Teachers
Workings: If 3/5 are female then 2/5 are male. 2/5 = 36 males 36 divided by 2 = 18 so get the one portion. to find out how many women: 18 x 3 (due to probability being 3/5)= 54 total teachers = males + females 54+36 = 90.
