A boy has 10 red and 10 blue marbles. He only needed to take out 15. i. What is the probability of choosing 10 marbles that is blue and 5 marbles are red? The boy bought new marble, and now he has 100 marbles in total. He has 30 red, 50 green, and 20 blue from the marbles. What is the probability that a randomly chosen marble is new OR green? If the boy wants to choose 10 marbles. The probability he will get the marble are new is 0.8, and the probability for the boy to get red and new is 0.24. Find the probability for the marble to be red given the marble is new? i. ii.

A UTM received 1000 applications for the undergraduate program every semester. Of all applicants, 150 had a CGPA score above 3.70. 520 applicants had a CGPA score between 3.50 and 3.70. 100 applicants had a score between 3.00 and3.50. All other applicants had a score lower than 3.00. i. What probability will a randomly selected applicant have a score lower than 3.00? If this semester, the total of students who get the CGPA score lower than 3.00 is 20% of the total student received, and the number of the other students who get CGPA above 3.50 is the same. Find the number of students who get CGPA ii. between 3.00 and 3.50?
