Calculate independent & dependent probabilities like a pro! Practice with our 7th-grade math worksheets.

Match the definition to the correct term. If the outcome of one event does not affect the other event, the events are _. Independent Events _ is the chance of an event occurring. Probability If the outcome of one event does affect the other event, the events are _. Dependent Events Sort each probability into independent or dependent. Independent Event Spinning a spinner Flipping a coin Drawing a card and replacing it Dependent Event Drawing a red marble and then a green marble without replacement Choosing two different students from the class Drawing a king and then a queen without replacement There are 10 game pieces in a bag: 5 yellow, 2 red, and 3 green.You randomly select a game piece from above and do not put it back.

What is the probability you select green both times? 3 9 6 Two socks are drawn from a drawer which contains one red sock, three blue socks, two black socks, and two green socks. Once a sock is selected, it is not replaced. Determine each probability.
