A 10 question quiz has 5 true/false & 5 mutiple choice questions. Each mutiple choice question has 4 choices. If you guess on every question, find P(acing the test).
-----
5 true/false correct: 1/2^5 = 1/32
------
5 multiple choice correct: (1/4)^5 = 1/256
------
P(all correct) (1/2^5)(1/2^8) = 1/2^13 = 1/8192
