You can put this solution on YOUR website! A single card is drawn from an ordinary deck of cards. Find the indicated probabilities if the given information is known about the chosen card.
a. P (club/not a diamond)
If that slash means "conditional"
P(club|not a diamond) = 13/39= 1/3
----------------
If that slash means "conditional"
b. P (face card/king) = 4/4 = 1
=======================
If that slash does not mean "conditional" tell me what
it does mean.
=========================
A player rolls a single die. If an even number comes up, he wins that number of dollars. If an odd number comes up he loses that number of dollars. What is the expected value (mathematical expectation) of this game?
There are three even and three odd numbers on the die.
================
Let x be the number on the die and therefore the earnings or loss.
-----------
E(x) = $[(-1)+(2)+(-3)+4+(-5)+6](1/6]
E(x) = $[3](1/6)
E(x) = $(1/2)
The player can expect to win 50 cents
