A and B throw 2 dices. If A throws sum of 9, then Bs chance of throwin...
Explanation:
Given Information:
When A throws 9, it means the total of the two dice is 9.
Possible Outcomes for A throwing 9:
When A throws 9, the possible outcomes are (3,6), (4,5), (5,4), and (6,3).
Chances of B throwing a higher number:
Out of the 4 possible outcomes, there are 3 outcomes where B can throw a higher number than 9.
So, the probability of B throwing a higher number is 3 out of 6 possible outcomes (since there are 6 possible outcomes when two dice are thrown).
Calculation:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 3/6
Probability = 1/2
Therefore, the chances of B throwing a higher number when A throws 9 is 1/2.
Conclusion:
The correct answer is option 'A' (1/6) as B has a 1/6 chance of throwing a higher number when A throws 9.
