If A and B are independent events with P( A) = 0.60 and P( B) = 0.70, then P( A or B) equals: a. 1.00 b. 0.42 c. 0.88 d. 1.30
1 answer:
Answer:
The correct option is D
P(A or B) = 1.30
Step-by-step explanation:
Given two independent (or mutually exclusive) events with P(A) = 0.60, and P(B) = 0.70
P(A or B) = P(A) + P(B)
= 0.60 + 0.70
= 1.30
This is however absurd, as the probability of an event can only be less than or equal to 1, and not less than 0.

Answer:
A. No, this is not a valid inference because he asked only 20 families
Step-by-step explanation:
You cannot assume that those are the only families that would want to go; you have to ask all the families.
To get rid of the 3, you multiply the x/3 by 3 to get x by itself. But if you multiply one side you have to multiply the other. So x = 99
