Question 429764
Two questions are on a test. There are 4 multiple choice answers for each question, but only one is right for each question. 
What is the probability you will get both questions correct. 
1. A,B,C,D (Only one can be right) 
2. A,B,C,D (Only one can be right)
---
P(x = 1) = 4C1(1/4)(3/4)^3 = 4*(27/256) = 108/256
---- 
Probability of getting both questions correct? 
P(x = 2) = 4C2(1/4)^2(3/4)^2 = 6(1/16)(9/16) = 54/256
