Question on final quiz #9 II-A
YangBober - 2021年02月20日 Saturday 15:37
 

I got this one wrong and the question asked for the probability of 10 but in the answer key, it is saying for 11.

I am not sure if it is right or wrong so here it is.

Can someone explain whether the answer key is wrong or I am still just wrong


Thanks

Thanks for pointing this out. You are correct that event $B$ should be the sum is $10$. Note, however, that the rest of the solution is okay, as $B$ was correctly listed as $\{ (4,6), (5,5), (6,4)\}$.

Let us know if you have any additional questions.
