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?
