The probability that event a occurs is 0.4, and the probability that events a and b both occur is 0.25. if the probability that either event a or event b occurs is 0.6, what is the probability that event b will occur? a. 0.05b. 0.15c. 0.45d. 0.50e. 0.55

C.

Step-by-step explanation:

We have been given that the probability that event A occurs is 0.4, and the probability that events A and B both occur is 0.25. The probability that either event A or event B occurs is 0.6. We are asked to find the probability that event B will occur.

We have been given, and .

We will use the formula .

Upon substituting our given values in above formula, we will get:

Therefore, the probability that event B will occur is 0.45 and option C is the correct choice.

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
