 Lap   Why a timer is critical to improving your score
what is the prob that a randomly selected studenti is male with brown hair?

1-) 1/3 of students have brown hair
2-) 1/2 students are male.


Please detail your reasoning.

P = Probability of choosing Male AND probability of choosing brown hairs.

1/2*1/3 = 1/6
