A woman brought a complaint of gender discrimination to an eight-member human relations advisory board. The board, composed of five women and three men, voted 5-3 in favor of the plaintiff, the five women voting for the plaintiff and the three men against. Has the board been affected by gender bias? That is, if the vote in favor of the plaintiff was 5-3 and the board members were not biased by gender, what is the probability that the vote would split along gender lines (five women for, three men against)?
