Answer:
b. The number of digits in a randomly selected row until a 3 is found.
Explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Also, any random variable that meets certain conditions defined in a research study.
Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.
Choosing the wrong friends can lead to a range of problems. To begin with, if your buddies insult others or you, you may become accustomed to being treated badly and direct this energy onto your family. Bad friends may put pressure on you to do things you don't want to do, which could result in negative results. Friends who do not care about your well-being are unlikely to assist you, so you may distance yourself from your family, fearing that they share your sentiments and are uninterested in your well-being. Friends can be disrespectful about your family at times, and this can make you feel obligated to agree with them, which can lead to them being rude to their own family members.

Using the binomial distribution, it is found that there is a 0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.
For each friend, there are only two possible outcomes, either they go to the cafe, or they do not. The probability of a friend going to the cafe is independent of any other friend, hence, the binomial distribution is used to solve this question.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 3 friends, hence n = 3.
- They all go to the cafe with a 3/4 probability, hence p = 3/4 = 0.75.
The probability at least one goes is:
In which:
Then:
0.9844 = 98.44% probability that bohan goes to café georgia for a coffee today.
