4. A crowd contains 1000 people. 480 males and 520 females. Find the likelihood someone chosen at random is Female.
P(female) = 520/1000 = 0.52
-------------------------------------
5. Using the information from #4, find the probability that two people chosen at random without replacement are both females.
Ans: 520C2/100C2 = 0.2702
-------------------------------------
6. Using the information from #4, four people are chosen with replacement. Find the probability that they are chosen by gender EXACTLY in order as FFMM.
Ans: (1/2)^4 = 1/16
----------------------------
7. Using the information from #4, find the probability that two people are chosen without replacement that have the same gender.
Ans: [480C2 + 520C2]/1000C2 = 134940/499500 = 0.2702
