More than 4,000 years ago, people in ancient Babylonia used math to calculate how much land to use for farming and how much of each crop they harvested. They also
used math to calculate how much tax to charge people.
Today, we use algebraic tools such as writing and solving equations, systems of
equations, inequalities, and systems of inequalities to help us measure and interpret
real-world scenarios. What twenty-first century tasks do these tools help us manage?

Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a diamond or heart. (type an integer or a decimal rounded to three decimal places as needed.) (b) compute the probability of randomly selecting a diamond or heart or club. (type an integer or a decimal rounded to three decimal places as needed.) (c) compute the probability of randomly selecting queen or club. (type an integer or a decimal rounded to three decimal places as needed.)
