My sister Donna started a trading card collection last year, but unfortunately, she can’t seem to keep track of her cards. Recently she took all of her cards with her on the bus to school. On the way there, some bullying sixth graders stole ¼ of her cards. Then she dropped six cards in the gutter when she got off the bus. She went to class and lost 2/3 of her remaining cards when she passed them around during show-and-tell. Then she gave three cards to her best friend. The teacher, Mr. Purcell, had a stash of trading cards which he let her pick through, giving her enough to increase her total by 1/5. When she went to recess, she found eight cards on the playground. Then at lunch, she accidentally threw half of her remaining cards away in her lunch bag. When she came home, she had only ten cards left. How many cards did Donna have when she left for school?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
