Which of the following formulas is used to calculate the probability of independent events A and B?
2 answers:
<h2>Answer:</h2>
The formula that is used to calculate the probability of independent events A and B are:
D. P(A and B)=P(A)·P(B)
<h2>Step-by-step explanation:</h2>Independent events--
Two events A and B are said to be independent if the happening of one event do not affect the happening of the other event.
For example-- The probability of getting two heads on rolling a die two times.
Hence, the formula that calculate the probability of independent events A and B is given by:

Answer:
Correct choice is 2.
Step-by-step explanation:
We have been given a graph of the quadratic function. Now we need to use that graph to find the equation of the graph in vertex form. By the way given choices written in intercept form so to be accurate we are going to find the equation in intercept form.
from graph we see that x-intercepts are at 5 and -2.
we know that if x=a is x-intercept then (x-a) must be factor.
So (x+2)(x-5) is the factor.
when leading coefficient is positive then graph opens upward.
so that means leading coefficient is 0.4
Hence correct choice is 2.
Answer:
x y
15 -1
12 0
9 1
6 2
3 3
0 4
Step-by-step explanation:
This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.
This means for every 3 units made in the input, the function moves down 1 output.
x y
15 -1
12 0
9 1
6 2
3 3
