We roll a pair dice 10,000 times. Estimate the probability that the number of times we get snake eyes (two ones) is between 280
Natali5045456 [20]

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

z_{1} = (280 - 277.7)/16.4 = .14

z_{2} = (300 - 277.7)/16.4 = 1.35

Probablity (range)  

0.3573  

Z(low)=0.14        0.555766357

Z(upper)=1.36        0.91304644
