Step-by-step explanation:
<u>Conditional Probability</u>
Is a measure of the probability of the occurrence of an event, given that another event has already occurred. If event B has occurred, then the probability that event A occurs is given by:

Where
is the probability that both events occur and P(B) is the probability that B occurs.
Let's define events A and B for the question. There are 11 students that have a brother and 9 that have a sister. Two of those students have a brother and a sister.
We are given the fact that the selected student has a brother: this is the event that has already occurred, thus:
B = A student has a brother
A = A student has a sister
The probability that a student has a brother is:

The probability that the student has a brother and a sister is:

Thus, the conditional probability is:

Step-by-step explanation:
nah man. i dont get it either
It should be the second answer.
Reason:
-np-3≥7(c-4)
-np≥7c-28+3
-np≥7c-25
-n≥(7c-25)/p
N≤-(7c-25)/p
Answer:
1
Step-by-step explanation:
First, we can find the equation of the parabola. The standard form of a parabola is ax^2 + bx + c,
where c is the y-intercept. The y-intercept on the graph is -5, and every option starts with x^2, so the equation must be x^2 - 5. This rules out options 3 and 4.
Next, we can find the equation of the line. The options are all given in slope-intercept form: y = mx + b, where b is the y-intercept. The y-intercept on the graph is 1, and option 1 has 1 in the place of b. Therefore, option 1 is the answer.
