P(A)=0.40 p(b)= 0.50 p(A and b) = 0.10 what is p(b/A)? <br><br><br>plz help​
yawa3891 [41]

Answer:

The answer is C, 0.25.

Step-by-step explanation:

In order to find the probability of (B | A), you need to use this formula:

Conditional Probability (A has already occured)

P(B | A) = P(A and B)

                     -------

                      P(A)

If you subsitute in the values you get this:

P(B | A) = 0.10

               ------

               0.40

0.1 divided by 0.4 is equal to 0.25.

The graph of f(x)=2x^3+x^2-4x-2 is shown. How many of the roots of f(x) are rational
Alexeev081 [22]

We can one theorem to help us find rational roots of this polynomial.

2x^3 + x^2 - 4x - 2

We'll use Descartes' rule of signs.

Because there is 1 sign change, 1 of the 3 roots will be positive.

Now we can make the value of x -1 to see how many negative roots there will be.

-2  + 1 + 4 - 2

There are 2 sign changes, so we know there will be 2 negative roots.

Because of this, we should have 3 real, rational roots.
