Multiplication is an abbreviated form of addition.
For instance,
3 × 3 = 3 + 3 + 3 = 9
Answer:
25
Step-by-step explanation:
180-45=135 and 180-135=45
360 is the sum of all angles so:
360-105-135-45=75
3x=75
x=25
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
