D1: The following data represent the scores received on the 2015 SAT Mathematics Test, by gender:

200 - 290	33,987	31,462
300 - 390	121,664	142,491
400 - 490	242,281	297,876

700 - 800	39,184	36,475

For each of the circumstances below, explain (don't just compute) how you would find these probabilities and what rule you applied to calculate them.

1. If a test taker is randomly selected, what is the probability that the test taker is male?
2. If a test taker is randomly selected, what is the probability that the test taker scored between 400 and 690?
3. If a test taker is randomly selected, what is the probability that the test taker is female or scored 700 -800?
