If events A and B are independent, what must be true?A.) P(AB) = P(B)
anygoal [31]

Answer:

B.) P(A/B) = P(A)

Step-by-step explanation:

If two events, A and B are independent:

We have that:

P(A \cap B) = P(A)P(B)

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

Since they are independent:

P(A \cap B) = P(A)P(B)

Then

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)

So

P(B|A) = P(B), or either:

P(A|B) = P(A), and thus, the correct answer is given by option B.

Which is an equation of the line that
Ymorist [56]

Step-by-step explanation:

(5,2) & (10,-3)

the slope of the points are

y2 - y1 / x2- x1

-3-2/10-5

-5/5

-1

the mid point of the given points are

x= x1 + x2/2 , y= y1 +y2 /2

.

.

.

.

( , )

the equation of the line that passes through the given points are as

y+ y1 = m (x+ x1)

:. now put the value of the mid point in y1 and x1 and the value of slope in m

also find the mid point, it's hard to do it in a mobile without calculator and paper and pen

8.0464x10^-7 = <br> answer in decimal notation
Charra [1.4K]
To convert 8.0464x10^-7 from scientific notation to decimal notation, you need to move the decimal point to the left seven times.
Therefore the answer is:

0.00000080464

Note: 10^-7 equals 1/10^7
8.0464x10^-7 can be rewritten as:
8.0464/10^7 (i.e. divide 8.0464 by 10000000)
which results: 0.00000080464
