1. The formula for calculating Mean or Expected value is 2. I have discovered that the Expected Value E(X) is only the of random variable X. It's occasionally called a because more 450) frequent values of X are weighted more highly in the average. . The variance of a discrete random variable X is dened . The standard deviation of X is dened to be the square root of the variance of X. In symbol it expressed into . The variance cannot be , because it is an average of squared . . 'J quantities. Hence, 0"x 2 ? and a} (X) 2 ? - What I Can Do LET'S DO FAMILY PLANNING! Things to do: 1. Create a short script as if you are with your dream partner in life and you both talking about Family Planning. . During your planning, specify in your decision how many girls (G) and boys (B) in the family you both want to have. Consider also your random variable X stand for. . After your planning, construct a probability distribution of whatever decision you had. . Based on the probability distribution table, illustrates the following: a. Mean or Expected Value; b. Variance; and (3. Standard Deviation. Share your output to the Class Group Chat through Image or Video Presentation
