Suppose you and a friend are playing a game that involves flipping a fair coin 3 times. Let the number of times that the coin shows heads You have previously shown that all conditions have been met and that this scenario describes a binomial setting Determine the value of n and p and calculate the mean and standard deviation of X Round the standard deviation to three decimal places

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

step-by-step explanation:

find the magnitude of the trig term
