Two dice are thrown and the sum of the numbers appearing on the dice is observed to be a multiple of . If is the conditional probability that number has appeared atleast once, then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Given, Two dices are thrown so total sample space will be 36, Now let the sum of numbers appearing on dice be a multiple of 4 be event A, So outcomes of event A will be 2,2,1,3,3,1,5,3,3,5,6,2,2,6,4,4,6,6→9 So probability will be PA=936=14 Now let the event 4 has already…
