1 because he HAD 5 and if he gave his friend 4 than he has 1 left, 5-4=1 my friend.
Oh okie so sorry sorry about the delay in
It will take Marvin 12 days to exersise for 576
To answer this question, use permutation since the order of the letter matters. There are 7 letters and only 4 are to be used for the code. This is a permutation of 7 taken 4 (7P4) which is equal to 840. Thus, the sample space is 840.
For the next questions, there are 3 vowels for as the first letter, only 6 letters are available for the second, 5 on the next, and 4 on the last. Multiplying these numbers give 360. To solve for probability, divide this number with the sample space. Thus, the answer is 3/7.
I would have to say 85 but thats just a guess.
