Probability Theory and Distriutions

If A and B are any two events of a sample space S, then

 

• P (A) + P (B)

• P (A) – P (B)

• P (A) P(B)

1.      If A and B are events of a sample space S such that A ⊆ B then

 

• P (A) = P (B)

• P (A) < P (B)

• 0.5

•   0.8

• 0.1

• 0.2

• Mutually disjoint

• Exhaustive

• Independent

• not Independent

• 1/2

• 1/3

• 1/6

• 2/6

• 25/26

• 23/26

• 29/26

• 5/6

Let A and B be two events with P (B) ≠ 0. A is said to be independent of

B if P (A|B) = __________.

 

• P (A)

• P (A) P (B)

• P (B)

  Say True or False.

If A and B are independent events then A and  are also independent.

• True

• False

   If A, B, C are mutually independent events then
