10. The table below shows the results of a survey where participants were asked if they are a Total Broncos fan and how many siblings they have. Use the table to answer the questions 10-12 3-5 6 or more 0-2 Broncos Fan Not A Broncos Fan Total Suppose we randomly select someone from the table: a. Find the probability that person is a Broncos fan. b. Find the probability that person is not a Broncos fan. c. Find the probability that person has 6 or more siblings. d. Find the probability that person has at least 3 siblings. e. Find the probability that person has at most 5 siblings. f. Find the probability that person is a Broncos fan and has 3-5 siblings g. Find the probability that person is not a Broncos fan and has 6 or more siblings. h. Find the probability that person is a Broncos fan or has 0-2 siblings.Explanation / Answer
Solution:
( a )
probability that person is broncos fan = 14/24 = 0.5833
( b )
probability that the person is not a broncos fan = 10/24 = 0.4166
( c )
probability that the person has 6 or more siblings = 10/24 = 0.4166
( d )
probability that the person has atleast 3 siblings = 18/24 = 0.75
( e )
probability that the person has atmost 5 siblings = 14 / 24 = 0.5833
( f )
probability that the person is broncos fan and has 3-5 siblings = 6/24 = 0.25
( g )
probability that the person is not a broncos fan and has 6 or more siblings = 7/24 = 0.2916
( h )
probability that the person is a broncos fan or has 0-2 siblings = ( 1 + 5 + 6 +3 ) / 24 = 15/24 = 0.625
( i )
probability that the person is not a broncos fan or has 6 or more siblings = ( 1 + 2 + 7 +3 ) / 24
= 13/24 = 0.5416
