A Head Teacher Is Interested in Unconscious Bias in Teacher

A head teacher is interested in unconscious bias in teacher recruitment in schools.There were two posts and seven candidates,four men and three women.Theoretically,all the candidates have an equal probability of being hired as they all match the selection criteria.However,the head teacher has data that suggests that it is more likely that women will be hired based on data from across the schools sector and within her own school.However,the head teacher has implemented many equality initiatives within her school and therefore wants to determine the probability that still no men will be hired.What formula could she use to determine this probability and assess the impact of unconscious bias in her school's recruitment?

A) NHST
B) Bayes' theorem.
C) Pearson's r
D) Cronbach's Alpha
