1)if you are recieving 8 books as gifts and there are 27 different titles how many possible selections are there if each title can only be used once?:
the way I remember it you should set it up like this if g=gift
only thing is do I multiply those or add or what? also if anyone knows how it would be entered on a TI-83 plus that would help as well
2)If a fair die is rolled what is the probability that the number rolled is 5 given that it is odd
P= favorable/total outcoms p=1/6 also does the given it is odd part have any effect on the problem or is it extra info?
