the percents intending to vote for the candiate by income level
low: 80%
midrange: 45%
high: 40%


Assume that 20 % of the population belongs to the low income level, 60% belong to the mid range income level, and 20 % belong to the high income level. Suppose a voter is selected at random.

What is the probability that a voter belongs to the high income level, given that the voter intends the vote for this candidate?
If possible please show me how you get the answer too! stats is a killer

The answer is .157 or 15.7%, I just don't know how to get that.

.80*.20 are low income who intend to vote for the candidate = .16
.45*.60 are mid income who ''' = .27
.40*.20 are high income who ''' = .08
IF there were 100 people in the sample, then 16+27+8 would be voting for the candidate or 51.
8/51 = .157
