Answer 1

1) 5!/6! = 5!/6*5! = 1/6

Answer 2

can you tell me what formula we are using?

Answer 3

probability = Number of ways event/ The total number of possible outcomes

Answer 4

thanks

Answer 5

really having a hard time

Answer 6

for this case, to find of the even Comic D will perform first, we use permutation concept, 5P5

Answer 7

how about question 2?

Answer 8

2) P=4!/6! = 4!/6(5)(4!) = 1/30

Answer 9

i was totally off on my answer

Answer 10

3) 1/6! = 1/720

Answer 11

4) P = 2*5!/6! = 2/6 = 1/3
