) Approximately 5 out of 8 students at Tina's school are on a sports team. Two students design accurate simulations to determine how many
students would need to be randomly selected before 9 students who are
on a sports team are found.
A student places 60 blue marbles in a bag to represent students who are
on a sports team and places some yellow marbles in the same bag to
represent students who are not on a sports team. The student will
randomly select a marble, record the color, and return the marble back to
the bag. How many yellow marbles does the student place in the bag?

Design an er diagram for keeping track of information about votes taken in the u. s. house of representatives during the current two-year congressional session. the database needs to keep track of each u. s. state's name (e. g., texas', new york', california') and include the region of the state (whose domain is {northeast', midwest', southeast', southwest', west'}). each congress person in the house of representatives is described by his or her name, plus the district represented, the start date when the congressperson was first elected, and the political party to which he or she belongs (whose domain is {republican', democrat', 'independent', other'}). the database keeps track of each bill (i. e., proposed law), including the bill name, the date of vote on the bill, whether the bill passed or failed (whose domain is {yes', no'}), and the sponsor (the congressperson(s) who sponsored - that is, proposed - the bill). the database also keeps track of how each congressperson voted on each bill (domain of vote attribute is {yes', no', abstain', absent'}). additional information:
