WebJul 3, 2015 · Probability of choosing 1 icecream out of a total of 6 = 4/6 = 2/3. So the final probability of choosing 2 chocobars and 1 icecream = 1/2 * 3/7 * 2/3 = 1/7 . Probability Example 3. When two dice are rolled, find the probability of getting a greater number on the first die than the one on the second, given that the sum should equal 8. Solution WebThe mean clotting time of blood is 7.45 seconds with a standard deviation of 3.6 seconds. What is the probability that an individual's clotting time will be less than 3 seconds or greater than 13 seconds? Assume a normal distribution. This problem can be solved using technology or the table for the standard normal curve.
