Question 1:

Assume that a fair die is rolled. The sample space is

1,2,3,4,5,6, and all the outcomes are equally likely. Find P less than 3 . fraction or whole number.

P(Less than 3) = Blank.

Question 2:

If P(A) = 0.53 , P(B) = 0.5, and P (A and B) = 0.41 , find P (A or B).

P (A or B ) = Blank.

Question 3:

(This one I was confused on)

Flawed parts: On a certain day, a foundry manufactured 612 cast aluminum parts. Some of these had major flaws, some had minor flaws, and some had both major and minor flaws.

	Minor Flaw	No Minor Flaw
Major Flaw	25	31
No Major Flaw	80	476

(Round all to four decimal places it asks)

(a) Find the probability that a randomly chosen part has a major flaw.

P(major flaw) = Blank. (b) Find the probability that a randomly chosen part has a minor flaw.

P(minor flaw) = Blank. (c) Find the probability that a randomly chosen part has a flaw (major or minor).

P(Major flaw or Minor flaw) = Blank. (d) Find the probability that a randomly chosen part has no major flaw.

P(No major flaw) = Blank.
