1) Which of the following best define probability? a) A way to guess the answer to a math problem b) The number of times an event has happened in the past c) A type of shape used in geometry d) The measure of how likely an event is to happen 2) Is the probability of getting an even number when a die is rolled 1/2? a) Yes, because there are 3 even numbers (2, 4, 6) out of 6 total numbers, so the probability is 3/6 = 1/3. b) Yes, because even numbers make up half of the numbers on the die, so the probability is 3/6 = 1/2. c) . No, because the probability is 1/6 since only one number comes up when the die is rolled. d) No, because the probability should be 1/3 since only one number can come up at a time. 3) . In a Grade 8 Makiling class with 14 males and 16 females, what is the chance that the teacher will choose a boy to answer on the board? a) The probability is 14 out of 30, or 14/30, which shows the number of males compared to the total students. b) The probability is 7/15 because 14/30 can be simplified to 7/15, showing the simplified chance of calling a male student. c) The probability is 16 because there are 16 female students. d) The probability is 14 because there are 14 male students. 4) Your teacher asked you, from a standard deck of cards, which probability should you give for drawing a queen? a) The probability is 4/52 = 1/13, which is the ratio of queens to total cards b) The probability is 4/52 = 1/12, which is the ratio of queens to total cards c) The probability is 13/52 = 1/4, which is the ratio of queens to total cards d) The probability is 13/52 = 1/3, which is the ratio of queens to total cards 5) You have a bag with 5 red balls and 3 green balls. You draw one ball at random. What is the probability of drawing a green ball? a) 3/8 b) 4/8 c) 5/8 d) 1/8
