Sign- The Classroom Mrs. Congello has decided to spruce up her classroom for next year. Since her students have been away from school for so long. she thought that they would really appreciate a clean, updated and fun classroom to start off next yearl Answer the questions below. Be sure to SHOW ALL WORK and INCLUDE PROPER UNITS. The classroom has the dimensions shown: 789 808 9.1 m 10.3 m 3.2 m 1) Mrs. Congello would first like to paint the walls of the classroom. If 1 gallon of paint covers 372 square meters, how many gallons of paint will she need to purchase? 2) She would also like to replace the tile floors with a fun and colorful carpet. How much money will she need to spend if the carpet is $13.99 per square meter? 3) Mrs. Congello wishes she can turn her classroom into a pool for just one day. The first day of school would be just one big pool party! If she could, how much water would che need to all the classroom?
Addition Rule of Probability
It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.
Expected Value
When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known as the expectation, is denoted by: E(X).
Probability Distributions
Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosing a card. Each of these events has multiple possibilities. Every such possibility is measured with the help of probability. To be more precise, the probability is used for calculating the occurrence of events that may or may not happen. Probability does not give sure results. Unless the probability of any event is 1, the different outcomes may or may not happen in real life, regardless of how less or how more their probability is.
Basic Probability
The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the probability value 1 indicates that the event will occur. Sum of the probability value must be 1. The probability value is never a negative number. If it happens, then recheck the calculation.
