P(A) = 0.36
P(B) = 0.25
P(A and B) = 0.09
Notice how P(A and B) = P(A)*P(B) = 0.36*0.25 = 0.09
So because P(A and B) = P(A) *P(B) in this case, this means A and B are independent events. In other words, the fact that A occurs does not alter the probability of event B.
Answer: independent
Answer:
(x -2) is a factor
Step-by-step explanation:
The factor theorem tells you that (x-2) is a factor of g(x) if g(2) = 0.
g(2) = 2·2³ -5·2² +2 +2 = 16 -20 +2 +2 = 0
Since g(2) = 0, (x -2) is a factor of g(x).

The graph shows us the complete factorization is ...
g(x) = (2x +1)(x -1)(x -2)
0-9 = 10 numbers
1st digit can be 1 0f 10
2nd digit can be 1 of 9
3rd digit can be 1 of 8
4th digit can be 1 of 7
10 * 9 *8*7 = 5040 different combinations
