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.

The number of students attending the game

A total of 120 adults and students attended a school volleyball game. Each
adult paid $2.50, and each student paid $1.00. The total paid by the adults
and students attending the game was $189.
Which of the following systems of equations can be used to find a, the
number of adults attending, and s, the number of students attending the
game?
2.5a+s
= 120
= 189
a +s
2.5a +s
= 120
1 3.5a + 3.5s
= 189
= 120
= 189
a +s
2.5a +2.5s
a +s
2.5a + s
= 120
= 189

please do the last question(Q3) as well Define a game as follow: you begin with an urn that contains a mixture of black and white balls, and during the game you have access to as many extra black and white balls as you need. In each move of the game, you remove two balls from the urn without being able to see what colour they are. Then you look at their colour and do the following: If the balls are the same colour, you keep them out of the urn and put a black ball in the urn. if the balls are different colours, you keep the black one out of the urn and put the white one back into the urn. Each move reduces the number of balls by one, and the game will end when only one ball is left in the urn. In this you will figure out how to predict the colour of the last ball in the urn and prove your answer using mathematical induction. Q1) Draw diagrams to map out all the possibilities for playing the game starting with two balls in the urn, then three balls, then four balls. For each case…

California Lotto officials want to try out a new "big wheel" game. This new game actually consists of two big wheels (spinners). The contestants spin Spinner 1, and then immediately after, they spin Spinner 2 to determine the "multiplier." When both spinners have stopped turning, the dollar amount shown on Spinner 1 is multiplied by the "multiplier" on Spinner 2 and the contestant wins that much money. $100800 20 50 150dp $1000 0.5 135° s5000 100 Spinner 1 Dollars Spinner 2 Multipliers What is the probability of winning the largest amount of money?

Zara and Sue play the following game. Each of them roll a fair six-sided die once. If Sue’s number is greater than or equal to Zara’s number, she wins the game. But if Sue rolled a number smaller than Zara’s number, then Zara rolls the die again. If Zara’s second roll gives a number that is less than or equal to Sue’s number, the game ends with a draw. If Zara’s second roll gives a number larger than Sue’s number, Zara wins the game. Find the probability that Zara wins the game and the probability that Sue wins the game. Note: Sue only rolls a die once. The second roll, if the game goes up to that point, is made only by Zara.
