<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:
Simplifying:
Given problem;
Inequality equation;
< 6
Before we solve, let us first translate this problem.
It simply states that for what value(s) of x will the expression be less than 6.
To find this value, we can simply carry out the normal mathematical simplification.
Simply multiply both sides by 16 to reduce the fraction;
16 x () < 6 x 16
On the left hand side, 16 will cancel out;
x < 96
Any value for which x is less than 96 will make the solution of this problem less than 6.
For example, 95;
= 5.93
This value is less than 6
