What is the probability that they will win 2 out of the next 3 games? Don't forget to add in the chance of failing. A coin is tossed 5 times. What is the probability that 3 out of the next 5 tosses will be heads? 12­7 Normal Distributions Normal Distributions show data that vary randomly from the mean. The pattern the data form is a bell­shaped curve (called a normal curve) 1 Std Dev = 68.2% 2 Std Dev = 95.4% 3 Std Dev = 99.7% In a Group of 300 People, What number of the people should be within +/­ 1 Standard Deviation of the Mean?
