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.
Answer: It =5
Can I get brainliest please and thank you :)
I think it’s the third one I’m srry if u get it wrong sksk
I think this is the correct answer
2+ 928 <span> = 2 + 0.0928 = 2.0928
