Madison enjoys the game of golf. he knows that he will one-putt a green 15% of the time, two-putt 20% of the time, three-putt 35% of the time, and four-putt 30% of the time. find the expected value for the number of putts madison will need on any given green. make sure to write down the entire equation that you used to solve this problem.

The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.

the correct answer is d

hope this

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76
