Question 1173280: According to a survey, 49% of U.S. adults have purchased a state lottery ticket in the past 12 months. Of these 49%, about 27.5% have annual incomes less than $36,000.
Find the probability that a randomly selected U.S. adult purchased a state lottery ticket in the past 12 months and has an annual income less than $36,000.
Find the probability that a randomly selected U.S. adult who purchased a state lottery ticket in the past 12 months has an annual income greater than $36,000.
Would it be unusual for a randomly selected U.S. adult to have purchased a state lottery ticket in the past 12 months and to have an annual income less than $36,000? Explain.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! This is the product of 0.49 and 0.275=0.13475
For greater than $36,000, the product of 0.49 and 0.725=0.35525
it is not common for one to have an income of < $36,000 but it is almost 1 in 7, so it is not rare, either.
