Answer:
Events A and B are not independent.
Step-by-step explanation:
In order for two events to be independent, the following relationship must be true:
The intersection between events A and B is the outcome that Bob and Alice have exactly one girl, the probability is:
For event A, the possible outcomes are having one or two girls:
For event B, the possible outcomes are having none or one girl:
Therefore, P(A) x P(B) is:
Since P(A) x P(B) ≠ P(A∩B), events A and B are not independent
Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Find the value of XY
see the attached figure to better understand the problem
we know that
-----> by segment addition postulate
If X is the midpoint WY
then
substitute in the formula above
substitute the given values and solve for XY
Subtract 6 both sides
Divide by 2 both sides
Rewrite
Answer:
<u><em>note:</em></u>
<u><em>find the attached solution</em></u>
Your answer is the first choice,
x = 9/2
