Answer:
f(-1)=6×(-1)^-4=6/(-1)^4=6/1=6
12.5%. there is a 1 in 8 chance that all three times it will land on heads.
Easy
so remember
4 aces in a deck
probability =(desired outcomes)/(total possible)
total possible=52
4/52=1st card
then since he picked 1 out the total possible is and assuming he drwe an ace 3/51
so the answer is 4/52 times 3/51=1/221
Perimeter = 2l+2w in this case. So 16+12, 28 feet is your answer!
