Illustrating and Calculating the Mean and Varianceof Discrete Random VariableRead and analyze the situation given below:Mr. Cresente Umali, a Mathematics teacher, regularly gives aformative assessment composed 5 multiple choice items. After theassessment, he used to check the probability distribution of the correctresponses and the data is presented below.Test Item ProbabilityP(X)0.030.050.1230.3040.280.22Based on the data above, observe, analyze and answer the followingquestions:1. Is the probability of x lies between O and 172. What is the sum of all probabilities of x?3. Is there a negative probability? Is it possible to have a negative probability?yes4. What is the average or mean of the probabilities of discrete randomvariable?5. What are the variance and the standard deviation of the probabilitydistribution from the data abave?llAnalysisThis time, you need to reflect on the following aquestions because it willhelp you to understand the appropriate way on illustrating and calculating themean, variance and standard deviation of a discrete random variable, Answer thefollowing questions:1. How did you find the given activity?2. Were you able to get the correct answer for each question? if yes, VeryGood! If not, which question/s you find difficult?3. What mathematical skills help you to answer all 5 questions?4. Do you think the concepts that you will acquire in thie mndule would ba目helpful to solve real-life problems?Abstraction
