22% of voters support the Conservatives, 30% Labour, 14% some other party, with 34% not supporting
a political party. When asked what party they support, voters either answer truthfully or
refuse to answer; the probability of a refusal is 25% for a Conservative supporter, 20% for a Labour
supporter, or 5% for everyone else.
(i) What proportion of voters say that they support the Conservatives?
Got an Answer = 0.165 = 16.5%
(ii) Of those who do answer, what proportion claim to be Conservative supporters?
Stuck Here
P(Conservatives|They answer) = 0.165/I don't know what goes here
(iii) Of those who refuse to answer, what proportion actually support a political party? [5 marks]
- No idea aswell
It is really weird how I can questions harder than this on different topics but this probability stuff, I just dont get
Thanks
