Unit 6 Practice
Use the 2-way table above to answer questions 1-4.
1) Based on the survey results above, what is the probability that a person sampled was female? Initialize the value of 'pFemale' below.
2) Based on the survey results above, what is the probability that a person sampled stated they felt they were 'overweight'? Initialize the value of 'pOverweight' below.
3) Based on the survey results above, what is the probability that a person sampled is a male AND felt they were 'overweight'? Initialize the value of 'pMAndO' below.
4) Based on the survey results above, given that a person believes they are underweight, what is the probability the person is a male? Initialize the value of 'pMGivenU' below.
Use the Venn Diagram above to answers questions 5-8:
5) What is the probability A or B? Initialize the value of 'pAOrB' below.
6) What is the probability of not A and not B? Initialize the value of 'pNeitherAB' below.
7) What is the probability of A given B? Initialize the value of 'pAGivenB' below.
8) What is the probability of B given A? Initialize the value of 'pBGivenA' below.
Use the following tree diagram for questions 9-12:
9) What is the probability of A and not B? Initialize the value of 'pANotB' below.
10) What is the probability of A? Initialize the value of 'pA' below.
11) What is the probability of A or B? Initialize the value of 'pAOrB' below.
12) What is the probability of A given B? Initialize the value of 'pAGivenB' below.
