Question 1042809: 09-30-2011, 09:11 PM
Angus reid conducted a survey of adult canadians finding that over all 56% supported the legalization of marijuana. the percenatage of support was different among voters for the three major parties (in the table below). for instance 17% of people both supported legalization of marijuana and also were conservative voters

conservative liberal Ndp
Supported 17% 21% 18%
Opposed 26% 9% 7%
Not sure 1% 1% 0%

1) what is the probability that a liberal voter opposed the legalization of marijuana?
2) what is the probability that someone who supported the legalization of marijuana was an NDP voter?
3) suppose i talk to 5 people about support for the legalization of marijuana at a meeting of the liberal party where everyone is a liberal voter. what is the probability that none of the 5 people supports the legalization?
4) is voting conservative independent of opposing the legalization of marijuana?
5) are voting conservative and opposing the legalization of marijuana mutually exclusive?

-------------------------------
conservative liberal Ndp Totals
Supported 17% 21% 18%....56%
Opposed 26% 9% 7%.....42%
Not sure 1% 1% 0%..... 2%
Totals........44%........31%.......25%.....100%
------------------------------------------------------
1) what is the probability that a liberal voter opposed the legalization of marijuana? :: 9/31
2) what is the probability that someone who supported the legalization of marijuana was an NDP voter?:: 18/56
3) suppose i talk to 5 people about support for the legalization of marijuana at a meeting of the liberal party where everyone is a liberal voter. what is the probability that none of the 5 people supports the legalization?::0.79^5
4) is voting conservative independent of opposing the legalization of marijuana?
Check P(vote cons)*P(legalize mara) = P(vote cons|legalize mara)
0.44*0.56 ?=? (0.17/0.56)
not equal, so not independent
-----------------------------------
5) are voting conservative and opposing the legalization of marijuana mutually exclusive?
I'll leave that to you.
