Two number cubes are rolled for two separate events: All of the combinations of numbers on both cubes that give a sum less than 10.
All combinations of numbers on both cubes that give a sum that is a multiple of 3.
a. In terms of a reduced fraction, find the conditional probability of B given that A occurs first. Fill in the blanks P( __ l __ ) = __ / __
b. Complete the conditional-probability formula for event B given that event A occurs first by writing A and B in the blanks: P( __ l __ ) = P( __ ∩ __ ) / P( __ )
c. List the members of the sample space for event A ∩ B.
d. List the members of the sample space for event A.

How is the interquartile range calculated?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
