Determine the number of sitting arrangements
The number of girls are 5, of which 2 must be seated together.
<em>First, Emma and Lily can be arranged in 2! ways</em>
Next, we consider Emma and Lily as one, so there are (5 - 1) girls left to be arranged.

Total number of ways is then calculated as:
<em>Hence, there are 48 ways</em>
Answer:
And we can find this probability with this way:
Step-by-step explanation:
For this case w ehave the following info given:
represent the sample mean
represent the sample variance
represent the deviation
represent the sample mean selected
For this case we want to find the following probability:
And since the sample size is large enough we can use the following distribution for the sample mean:
And we can use the z score formula given by:
And we can find the z score for the value 135.7 and we got:
And we can find this probability with this way:
