As a prospective teacher, communication skills occupy a very important position, because communication skills will affect the understanding of the students they teach. With good communication skills, a teacher can convey his ideas or ideas well, on the other hand, if his communication skills are not good, the ideas or ideas will not be conveyed perfectly. Communication skills provide opportunities for students to convey their ideas both verbally and in writing and learn to respect the opinions of others. Communication is a process of giving and conveying meaning in an effort to create mutual understanding. Communication is a process, not a static thing, so communication. Students from well-known universities in Jakarta are students who are prepared to become prospective teachers in elementary schools. Thus, these students need to be prepared and trained from an early age to develop communication skills. This is because to form students with good communication skills requires a long time of habituation and cannot be formed instantly. Therefore, the communication ability test was conducted on 50 students to assess this. The test results are attached in the following table. 65 98 82 51 81 82 61 60 64 83 69 82 97 51 58 93 58 75 82 70 78 94 97 53 72 88 64 86 100 90 100 80 100 96 78 61 67 78 66 76 87 59 90 74 84 88 60 51 72 65 Based on the above case, make it a.

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.
