3 Dice are rolled, what is the probability that they are all different numbers and one of them lands on a 6?
Total Number of Events = 63= 216
Favorable Events:
One of the 3 dice = 6. So, the dice with 6 can be selected in 3 ways.
One of the other 2 dice an take any of the remaining 5 values.
Next dice can take any of the remaining 4 values.
These 2 dice can be permuted in 2 ways.
So,
Number of ways that they are all different numbers and one of them lands on a 6 = 3 X 5 X 4 X 2 = 120 ways
So,
Probability that they are all different numbers and one of them lands on a 6 = 120/216 = 0.5556
So,
Answer is:
0.5556

1) Three dice are rolled. If each lands on a different number, find the probability that one is 3? 2) ) Three machines (A, B, C) manufacture screws. They manufacture 25%, 35%, and 40% of the screws, respectively. The output screws are defective at 2%, 3%, and 5%, respectively. If you choose a random screw produced at the factory and it is defective, what is the probability it came from each machine A, B, and C
