2. Find the probability distribution for flipping 4 coins, looking at the number of heads. Then, find the following: (a) Find the mean of the probability distribution (b) Find the variance of the probability distribution (c) Find the standard deviation of the probability distribution 3. Find the probability distribution for rolling a pair of 4-sided dice. Then, find the following: (a) Find the mean of the probability distribution (using the sum of the rolls) (b) Find the variance of the probability distribution (c) Find the standard deviation of the probability distributionHe t 3-Unit Ill: Chapter 6 2 3 4 7 8 9 10 This Question: 2 pts This Test: 100 pts Time Remaining: 01:42:07 Fill in the blank. Finding probabilities associated with distributions that are standard normal distributions is equivalent to Finding probabilities associated with distributions that are standard normal distributions is equivalent to finding the mean of the distribution. finding the z-scores associated with the probabilities. finding the variance of the distribution. finding the area of the shaded region representing that probability Pronoun Question3.1.2 Understanding Pre x 3) business owners that starter + w X MATH 1340 C1608 2020WI Assignments 3.1.2 Understanding Probability 3.1.2 Understanding Probability Home Determine whether or not the distribution is a probability distribution and select the reason(s) why or why not.
