Ch 3: Assignment 01 Use Probability addition and subtraction nules as well as Binomial Distribution conc These are due after Binomial Distribution concepts are discussed but you can start working on them now solving using Intenectioncancepta 1) Using addition rule with blood Group Group B Group Group ories cat Table 1. describes the bloodgroups and A Rh types of 100 people (based on data from 35Rh+ 8Rh+ 4Rh+ 39Rh+ the greater New York Blood Program). Assume that 1 of the 100 subjects is randomly selected. Find the indicated probability: POgroup A or O or type Rh+) 2) Finding Complements a. Find P(A) given that POA) 0.0175 b. A Reuters/Zogby poll showed that 61% of Americans say they believe that life exists elsewhere in the galaxy. What is the probability of randomly selecting some one not having that belief? Slide 119 of 106

Explanation / Answer

1) P(group A or O or type Rh+) =(35+8+4+39+5+6)/100=0.97

2) P(Ac)=1-P(A) =1-0.0175=0.9825

b)probabilty to have some one who does not believe on that =1-0.61=0.39
