Elijah estimates that 80% of the email he receives could be classified as junk. To predict how many junk mail messages he might
receive out of the next 50 emails, he places 8 red and 2 blue marbles in a bag. He draws one marble at random from the bag and records its color before replacing it. He records the following results. BR RR RIRIR RR B BRRRR RR RBR RRB BR How can Elljah use the results of his simulation to predict the number of junk mail messages he will receive in the next 50 mails?

Here is the complete question
Find the volume of the parallelepiped with one vertex at the origin and adjacent vertices at (1, 0, -3), (1, 2, 4), and (5, 1, 0).
Solution
We find the volume of the parallelepiped by making a 3 × 3 column matrix whose columns are the corresponding coordinates of the vertices of the parallelepiped.
So, (1, 0, -3), (1, 2, 4) and (5, 1, 0)
The determinant of A is the volume of the parallelepiped. So,
detA = 1(2 × 0 - 4 × 1) - 1(0 × 0 - (-3) × 1) + 5(0 × 4 - (-3) × 2)
= 1(0 - 4) - 1(0 + 3) + 5(0 + 6)
= 1(-4) - 1(3) + 5(6)
= -4 - 3 + 30
= 23
So the volume of the parallelepiped is 23
