Im afraid you are stuck, the probability is too small to calculate.

This is a simple binomial distribution problem; either you roll an 8,9,10 or you dont. The probability of yes is 3/20 = .15 So, with 1M rolls, the expected mean 8-10 is 150000, with a standard deviaiton of sqrt(.15*.85*1000000) = 357. Since 100,000 is 5000 rolls or 14 standard deviations away from the mean, there is virtually no chance.
