Suppose that a box of DVDs contains 10 action movies and 5 comedies. a. If two DVDs are selected from the box with replacement, determine the probability that both are comedies. b. It probably seems more reasonable that someone would select two different DVDs from the box. That is, the first DVD would not be replaced before the second DVD is selected. In such a case, are the events of selecting comedies on the first and second picks independent events? c. If two DVDs are selected from the box without replacement, determine the probability that both are comedies.

Solution Summary: The author calculates the probability that both DVDs are comedies, if two movies are selected from a box with replacement.
Suppose that a box of
DVDs
contains
10
action movies and
5
comedies.
a. If two
DVDs
are selected from the box with replacement, determine the probability that both are comedies.
b. It probably seems more reasonable that someone would select two different
DVDs
from the box. That is, the first
DVD
would not be replaced before the second
DVD
is selected. In such a case, are the events of selecting comedies on the first and second picks independent events?
c. If two
DVDs
are selected from the box without replacement, determine the probability that both are comedies.
I circled the correct, could you explain using stoke
Use Euler's method to numerically integrate
dy
dx
-2x+12x² - 20x +8.5
from x=0 to x=4 with a step size of 0.5. The initial condition at x=0 is y=1. Recall
that the exact solution is given by y = -0.5x+4x³- 10x² + 8.5x+1
Find an equation of the line tangent to the graph of f(x) = (5x-9)(x+4) at (2,6).
