Answer:
0.3573 = 35.7%
Step-by-step explanation:
We roll a pair of dice 10,000 times so the mean and standard deviation is,
μ = 10000/36 =277.7 σ = ![\sqrt{10000*\frac{35}{36^{2} } } =16.4](https://tex.z-dn.net/?f=%5Csqrt%7B10000%2A%5Cfrac%7B35%7D%7B36%5E%7B2%7D%20%20%7D%20%7D%20%3D16.4)
= (280 - 277.7)/16.4 = .14
= (300 - 277.7)/16.4 = 1.35
