The probability that you get a head when tossing a coin The probability that you get chosen when all the names of your class are put in a hat and one is drawn out The probability that you get a number less than 7 when rolling an ordinary dice Match the correct to each statement 0 A 0.5 B 1 C a. it is an A? What is the probability that : A letter is chosen at random from the word MATHEMATICS b. it is an A or a T? c. it is a vowel The probability that she picks a black marble is ½ The probability that she picks a white marble is ¼ a. How many black marbles does she have? b. How many white marbles does she have? Jane has 20 marbles. Some are black, some are white and some are red Ms. Gilmer flipped a fair coin 120 times. It landed tails up sixty-five times. Describe what would likely happen if Jonathan flipped the coin another 120 times. There would be no change. The experimental probability would exactly match the theoretical probability The experimental probabilty would get further from the theoretical probablity. The experimental probability would get closer to the theoretical probability. Michael spins a spinner 10 times He gets the letter B six times. a. How many times would he expect to get the letter B if he did 30 spins? What is the experimental probability of getting blue? Green Results from choosing a disc 20 times 10 Yellow 3 Blue 7 John has a 3 sided spinner with 1,2 and 3 on it. He also has a 4-sided spinner with 2,4,5 and 6 on it.

The probability that team A will win the football match is 3/10. The probability that team A will lose is 6/10 What is the probability that player A will draw? the number 7 will appear more than the number 1. the theoretical probability is always less than the experimental probability the more times the cube is rolled, the closer the experimental probability gets to the theoretical probability the theoretical probability is always greater than the experimental probability. Which of the following statements is true? When rolling a number cube... Theoretical Probability Mr. Whatley rolled a fair number cube 40 times. The number 2 came up 10 times. Select the theoretical and experimental probability of rolling a 2 in simplest form. 10/40 1/4 1/6 1/8 Experimental Probability 1/6 1/5 1/20 1/4 |
