Which of the following iſ the best statement of the use of the addition rule of probability?
otez555 [7]

Answer:

Option C

Step-by-step explanation:

Addition theory of probability is used to determine the probability for union of two or more sets.

P(AUB) = P(A)+P(B)-P(AB) is the addition theory of probability for two sets A and B.

P(AUBUC) = P(A)+P(B)+P(C)-P(AB)-P(BC)-P(CA)

for 3 sets

This can be extended to any number of sets

So addition theory has nothing to do with independent events both occurring

Option c is the right answer.

Brandon is thinking of a number that is divisible by 6 and 8 . What is the smallest number that Brandon could think of
a_sh-v [17]

since

6 = 2 * 3 <--- two factors


8 = 2 * 2 * 2 <--- three factors


and since the "2" is there on each, then we can just use that instance of it once.


so instead of using 2 * 3 * 2 * 2 * 2, we'll use 2 * 3 * 2 * 2, and that is our LCD.


2 * 3 * 2 * 2 = 24.

What is the x and y intercept of 2.5x+8y=240 please show your work.
a_sh-v [17]

Answer:

The x and y intercept are (96,30)

Step-by-step explanation:

8y=240-2.5x

y=240/8-2.5x/8

y=30-0.3125x

The y intercept=30

The x intercept=96 thus 30=0.3125x,x=30/0.3125
