<h3>What is Probability?</h3>
The probability helps us to know the chances of an event occurring.

We know that for two independent events the probability of the two events occurring simultaneously is written as,

Now, as we know the probability of event m occurring also we know the probability of both events occurring simultaneously, therefore, the probability of event n occurring can be written as,

Hence, the probability of event n occurring is 0.3.

Answer:
0.4
Step-by-step explanation:
It would be C. A perpendicular slope means it has the opposite reciprocal slope, so 1/2 would turn into -2. Since there's only one option with -2 as a slope, C must be right.

Answer:
<u>B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed. </u>
Step-by-step explanation:
We make this conclusion based on these reasons:
- We are told that the "null hypothesis was rejected" after the <em>"manager feels that the pressure variability has changed.,</em> meaning the <u>null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.</u>
- <em>"changes in the manufacturing process"</em> form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.
It is based on the above reasons that the null hypothesis was rejected.
2x+ 3y=12
-2x -2x
3y=12-2x
Divide both sides by 3
Y=4-2/3 x
