Question 1049675: Here is the distribution of the adjusted gross income (in thousands of dollars) reported on individual federal income tax returns in a particular year. (Round your answers to three decimal places.)
Income < 15 15-29 30-99 100-199 ≥ 200
Probability 0.266 0.213 0.382 0.104 0.035
a) Given that a return shows an income of at least $30,000, what is the conditional probability that the income is at least $100,000?

P( I%3E=100000 | I%3E=30000 ) =
P%28I%3E=100000%29%2FP%28I%3E=30000%29++=+0.139%2F0.521+=+0.267, to three significant figures.
