Brokerage interview questions shared by candidates
On the phone was asked two simple probability questions. What is the probability of being dealt a pair of cards? What is the probability of rolling the same side of a dice three times in a row.
1/17 and 1/36
I think the second answer is 1/216 . Please explain ?
The reason it is 1/36 is because it does not specify which side it must be. Therefore the first roll does not really count. Once you take the first roll it will decide what you need to roll the next two times. Therefore the math is 1*(1/6)*(1/6)= 1/36. If they asked what is the probability of rolling a 6 three times in a row then it would be 1/216.
