A jar contains 38 red marbles numbered 1 to 38 and 44 blue marbles numbered 1 to 44. A marble is drawn at random from the jar. Find the probability of the given event. Please enter reduced fractions.

(a) The marble is red. P(red)=

(b) The marble is odd-numbered. P(odd)=

(c) The marble is red or odd-numbered. P(red or odd) =

(d) The marble is blue or even-numbered. P(blue or even) =

Expert Solution

total number of marbles = (38+44) = 82

number of red marbles = 38

number of odd red marbles = number of even red marbles = 38/2 = 19

number of blue marbles = 44

number of odd blue marbles= number of even blue marbles = 44/2 = 22

total number of even marbles = total number of odd marbles = 82/2 = 41

what is the probability? A jar contains 4 red marbles, numbered 1 to 4, and 12 blue marbles numbered 1 to 12. a) A marble is chosen at random. If you’re told the marble is blue, what is the probability that it has the number 2 on it? b) The first marble is replaced, and another marble is chosen at random. If you’re told the marble has the number 1 on it, what is the probability the marble is blue?

A jar contains 2 red, 3 green, and 6 blue marbles. In a game player closes their eyes, reaches into the jar and randomly chooses two marbles. The player wins the game if at least one of their marbles is red. Suppose it cost $1 to play the game and the winning prize is $3. Mathematically analyze this game and determine if it is in your financial interest to play the game.

A jar contains 4 Orange, 3 Blue, and 2 Green marbles. (a) Two marbles are selected one at a time at random without replacement, so order is observed in the sample. Define the events:A=“the first marble is Orange”, B= “the second marble is Orange”. Find(i)P(A), (ii)P(B), (iii)P(A∪B) =P(at least one Orange marble is obtained in the 2 draws). Show your work. (b) Suppose instead three marbles are chosen at random from the jar by choosing 3 in one hand; no...

Suppose we draw 3 marbles from a jar containing 7 red and 5 blue marbles. At each stage, a ball is drawn and its color noted. Then the marble is returned to the jar along with another two marbles of the same color. Given that the ﬁrst marble is red, what is the probability that the next two are blue?
