No they arn't. probability=number of favourable outcomes/number of possible outcomes. This method is valid provided the number of possible outcomes is finite and equally likely.The answers did 4/11P4
I can understand what they did but arent they wrong. 11P4 means that M and M arent distinct
one way: Prob (CAME) = (1/11)x(2/10)x(2/9)x(1/8) = 1/1980
Write out your methodMay I know why my way is wrong.
I understand how you got it, but why is my answer wayy off
2454 is the ways to arrange MATHEMATICS into 4 letters. Out of THEM CAME is part of them.
