Answer:
Step-by-step explanation:
We have been given that A and B are independent events. We are asked to find .
We know that if two events are independent, then .
Substituting our given values in above formula we will get,
Therefore, the probability of is 0.93.
When the events are independent
P(A∪B) = P(A) + P(B) - P(A∩B) . . . . where P(A∩B) = P(A)·P(B)
Substituting the given numbers, you have
P(A∪B) = 0.3 + 0.9 - 0.3·0.9
P(A∪B) = 0.93

Answer:
48%
Step-by-step explanation:Because its 48 out of 100
Here, we want to write the decimal as a percent
We first re-write as a fraction then multiply by 100%
We have this as;
#46
(m-8n)(m + 4n)
#49
(h - 8j)(h +11j)
