Answer:
This true because why ?
Step-by-step explanation:
Answer:
The probability that the three friends will meet in the same group is .
Step-by-step explanation:
We can define the following random variable:
"The friend was assign to the ith group"
This way and let's define . This way and the pdf for is given by:
We want that the three friends stay in the same group, in other words ,
But this holds for only one of the three groups and need to compute for all possible outcomes. Since the condition is that the three friends stay together, there are three possibilities: They are assign to the first group or the second group or the third group. We are not interested in one of them being assigned to another group. We want:
Which is very close to zero.
Not quite sure about the answer...maybe we should look for some better like problems....overall, Good luck. I'm sorry I tried to think the best I can..

To evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.
Assuming we are given the expression, 3x + (2x - 1), and we are required to evaluate the expression, the following shown below is how to evaluate the expression if we are told that x = 1.
- First step is to plug in the value of the variable, x, into the expression:
3(1) + (2(1) - 1)
3 + 2 - 1
- Using the order of operation, simply

Therefore, to evaluate an expression in maths, plug in he value of the variable, then simplify the expression following the order of operation.
