Answer :
The probability that in a group of 9 friends, at least two share the same astrological sign will be 0.985 as defined "Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution."
What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to express probabilities. The number of favorable events to all the events in an experiment is the ratio that makes up the probability formula. Theoretical probability, Experimental probability, and Axiomatic probability are the three categories into which probability can be divided.
Here,
The probability that in a group of 9 friends, at least two share the same astrological sign,
= 1 - the probability that all 9 friends have different astrological signs
=1-12P9/12^9
=1-79833600/5,15,97,80,352
=1-0.0154
=0.985
In a group of nine friends, there is a 0.985 percent chance that at least two of them will have the same astrological sign. "Probability is simply the likelihood that something will happen. The likelihood or likelihood of various outcomes can be discussed when we don't know how an event will turn out. The study of events that fit into a probability distribution is known as statistics."
