Answer #1

Consider an experiment with a standard 52-deck from which one
card is randomly selected and not replaced. Then a second card is
randomly selected. Define the following events: Event A = The first
card is a heart
Event B = The second card is a heart
a. Are these two events mutually exclusive? Why or Why not?
b. Are these two events independent? Why or why not?

Consider a standard 52-card deck from which one card is
randomly selected and not replaced. Then, a second card is randomly
selected. Define the two events as given. Complete parts a) and b)
below.
A = The first card is a club
B = The second card is a king
Are these two events mutually exclusive? Why or why not?
A.The events are not mutually exclusive. The event of selecting

A card is randomly selected from a standard, 52-card deck. The
denomination on the card is recorded so that the resulting sample
space is {A, 2, 3, 4, 5, 6, 7, 8, 9, 10, K, Q, J}. (In other words,
we ignore the suits.) (a) (5 points) Given that the card selected
displays some number from 3 to 10 (inclusive), what is the
probability that the value on the card is not a multiple of 4? (b)
(5 points) Suppose...

A crowd of people is in a room. One person from the room is
selected randomly. Suppose that we know that 1/5 of the people are
over six feet tall. 1/8 of the people have green eyes. The
probability that we select someone with either green eyes or who is
over six feet tall is given by P(T union G) = 0.25
a. Find the probability that the person selected has green eyes
and is taller than six feet.
b....

A study on crew teams analyzed the weights of randomly selected
rowers from the Oxford and Cambridge crew teams. From data
collected over past years, 8 Oxford and 8 Cambridge rowers were
randomly selected, and their weight their senior year on the team
was recorded. A curious crew fan wants to know if Oxford rowers
weigh more on average than Cambridge rowers.
a) What parameter should be used to address the researcher’s
question? µd µ1 -µ2
