Read attachment to understand the complete question
From the question, we have the following given parameters:
x = Amount paid for a second movie
--- Expected value of x
--- Standard deviation of x
Required
Determine the total amount paid for a second movie for 20 weeks
The required implies that we calculate the expected value for a duration of 20 weeks.
i.e.
If

Then:

Substitute 20 for n

Substitute 0.47 for E(x)


<em>Hence, the expected amount for a duration of 20 weeks is $9.4</em>
Given:
3 red dresses
2 white dresses
1 blue dresses
Probability that she will wear the blue dress at her party.
3 + 2 + 1 = 6 total number of outcomes.
There is only 1 blue dress so the number of ways it can happen is only 1.
probability of an event happening = number of ways it can happen / total number of outcomes
Probability = 1/6 or 0.166 or 16.6%
