II - Determine whether the distribution represents a PROBABILITY DISTRIBUTION or NOT.
6. P(1) - 1/19, P(2) = 10/19, P(3) = 5/19, P(4) = 5/19
7. P(1) = 0.25, P(2) = 0.75, P(3) = 0.35, P(4) = 0.65
8. P(1) = 1/8, P(2) = 3/8, P(3) = 3/8, P(4) = 1/8
9. P(1) = 0.15, P(2) = 0.27, P(3) = 0.29, P(4) = 0.29
10. P(1) - 10/33, P(2) = 1/3, P(3) = 12/33​
