Question

Question 6. A teacher is picked at random. 3/5 chance they are female. 36 are males. (3 marks) How many teachers are there altogether?
please show working out

thanks x

Answer 1

If there is a 60% chance there are female, then that must mean that 40% of the teachers are male. 
If 40% of all the teachers is 36, then 20% of all the teachers are 18 in number
So, when we multiply 20% by 5 (to get 100% = all the teachers), we get:
18 x 5 = 90 teachers in total
