Answer:

Some important points:

1) P(A) is always between 0 and 1

0 ≤ P ≤ 1

2) P(∅) = 0

3) P(S) = 1

a) What is the probability of any event that is sure to be occurring like Day of Judgment? Please provide answer supplemented with the reason for making the answer.

Ans: Probability of any event that is sure to be occurring is always equal to 1

P = 1

b) What is the probability of any event that cannot occur like preference of LU Brand by any Muslim?

Ans: Probability of any event that cannot occur is always 0.

P = 0

c) What is the probability of having an odd number when a dice is rolled?

S = {1, 2, 3, 4, 5, 6}

A = {1, 3, 5}

P(A) = 3/6 = 1/2 = 0.5

d) What is the probability of having a sum more than twelve when a pair of dice  rolled once?

S = {(1,1) , (1,2) , (1,3) , (1,4) , (1,5) , (1,6) ,

      (2,1) , (2,2) , (2,3) , (2,4) , (2,5) , (2,6) ,

      (3,1) , (3,2) , (3,3) , (3,4) , (3,5) , (3,6) ,

      (4,1) , (4,2) , (4,3) , (4,4) , (4,5) , (4,6) ,

      (5,1) , (5,2) , (5,3) , (5,4) , (5,5) , (5,6) ,

      (6,1) , (6,2) , (6,3) , (6,4) , (6,5) , (6,6)}

A = {∅}

P(A) = 0

e) What is the probability of having a sum of exactly eight when a pair of dice rolled  once?

A = {(2,6) , (3,5) , (4,4) , (5,3) , (6,2)}

P(A) = 5/36

f) What is the probability of having a sum of two or above when a pair of dice rolled  once?

Since, all the elements of set S are the elements of set A.

So, P(A) = 1

g) What is the probability of having a sum of eleven or above when a pair of dice  rolled once?

A = {(5,6) , (6,5) , (6,6)}

P(A) = 3/36 = 1/12

h) What is the probability of having queen if we draw a card at random from the pack of standard 52 cards?

Black

13 - Spades (Ace, 2, 3,...., 10, J, Q, K)

13 - Clubs (Ace, 2, 3,...., 10, J, Q, K)

Red

13 - Hearts (Ace, 2, 3,...., 10, J, Q, K)

13 - Diamonds (Ace, 2, 3,...., 10, J, Q, K)

Total no. of cards = 52

No. of favorable outcomes = 4

P(A) = 4/52 = 1/13

i) What is the probability of having a red color card if we draw a card at random from the pack of standard 52 cards?

Total no. of cards = 52

No. of favorable outcomes = 13 + 13 = 26

P(A) = 26/52 = 1/2

j) What is the probability of having queen of spade if we draw a card at random from the pack of standard 52 cards?

Total no. of cards = 52

No. of favorable outcomes = 1

P(A) = 1/52

k) What is the probability of having jack of club if we draw a card at random from the pack of standard 52 cards?

Total no. of cards = 52

No. of favorable outcomes = 1

P(A) = 1/52
