2. Incorrect. The answer is true, not false

 

The probability of a sizable amount of raw diamonds is p=0.6 and q = (1-p) = 0.4. Let the random variable X be the number of loads with a sizable amount of raw diamonds. Then,

 

  1. P(X = 9) = or 4.031%

 

  1. P(X = 10) = or 0.6047%

 

  1. P(X > 8) = P(X=9) + P(X=10)

P(X > 8) = 0.04031 + 0.006047

P(X > 8) = 0.046357 or 4.6357%
