Explanation Calculation: It is given that if Sarai downloaded a program of 3.6 MB to her computer and deleted a picture file of 7.2 MB such that when one downloads a file to a computer, memory space is taken up on the computer. When one deletes a file, one gains a certain amount of memory space on the computer. Let x be the amount memory space on the computer. The expression of the given situation in terms of integers is x + − 3.6 − 7 − .2 . Now simplify the expression x + − 3.6 − 7 −

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 …

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 choosi…

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 prob…

A scientist visited Amazon.com to purchase a book. To his amazement, he found the book priced at $23,698,655.93. He discovered that there were two vendors selling this book on Amazon, and each was using a computer to adjust the price based on the other seller's price. The result was that each day the first vendor's price was multiplied by 1.27. Assume that the initial price was $134.27, and determine how many days it took for the first vendor's price to reach the exorbitant figure above. Round your answer to the nearest day. days

In 2020, the pandemic caused by COVID-19 has created havoc all around the world. In a small island of population 1.2 million, there have been 30 new infections per day, on average, from January to August 2020 (total 243 days). All infected patients are required to stay in an isolated room at the quarantine facility for 14 days. How many rooms in the quarantine facility are occupied on average? (Round to nearest integer if necessary.) 1. Less than or equal to 99 2. Between 100 and 199 3. Between 200 and 299 4. Between 300 and 399 5. More than or equal to 400
