**2. Correct. The answer is true **

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,

a.
P(X = 9)
= _{}or 4.031%

b.
P(X =
10) = _{}or 0.6047%

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

P(X > 8) = 0.04031 + 0.006047

P(X > 8) = 0.046357 or 4.6357%
