Answer:
(d) is true
Explanation:
Given
Required
Which of the options is true
A) P(Brown) = P(Not Brown)
P(Brown) is calculated as:
P(Not Brown) is calculated as:
--- Complement rule
Solve
Both are not equal.
Hence, (a) is not true
(b) P(Brown) < P(Not Brown)
In (a) above
By comparison;
Because:
Hence, (b) is not true
(c) P(Not Brown) > P(Brown)
This is the same as (b)
i.e. both conditions represent the same.
Hence, (c) is incorrect
(d) P(Brown) > P(Not Brown)
In (b), we established that
Because:
Hence, (d) is true
Answer:
-1/4
Step-by-step explanation:
Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4
Answer: $ 400 .

Note that a "consol" is a "perpetuity".

To find the "PV" (Present Value) of a perpetuity, we use the equation: PV = C / r = Current value / interest rate
= $20 / (5%) = $20 / (5/100) = $20 / (0.05) = $400 .

So hmmm let's say, the pitcher has "x" cups when full
so, it was (3/4)x then 4 cups came out, went down to (2/3)x
now, if we subtract (2/3)x from (3/4)x, their difference will be the 4cups that were served
thus
and surely, you'd already know what "x" is
