For a biased die the probabilities for the diffferent faces to turn up are given below :
Faces : 1 2 3 4 5 6
Probabilities : 0.10 0.32 0.21 0.15 0.05 0.17
The die is tossed & you are told that either face one or face two has turned up. Then the probability that it is face one is :
Faces : 1 2 3 4 5 6
Probabilities : 0.10 0.32 0.21 0.15 0.05 0.17
The die is tossed & you are told that either face one or face two has turned up. Then the probability that it is face one is :
- 1/6
- 1/10
- 5/49
- 5/21
Answer
(D) 5/21
