What is the probability if I want to take 3 marbles in a row without return the marbles after the first pick and the result from the first to the third pick are blue, and yellow, and black? b. If I only want to pick 1 marble, What is the probability my pick is blue or red? c. What is the the probability if I want take 2 marbles in a row with return the marble from the first pick and the result of the first to second pick are black and yellow? 2. These are sample of ages of the patients at the pediatric ward of Hospital ABC;10,2,5,6,5,8,9,and 9. a. Find mean, median and mode. Mean : Median : Mode : b. Find variance. c. Find standard deviation Note: Show your solution
