Question

There are 5 lollipops.
Once a day, Joe licks on only one of them per day, and does this for 5 days straight.
What is the probability that Joe did not lick on exactly 1 of the lollipops?

Answer 1

that is way way wrong. nvm

Answer 2

have to think more

Answer 3

I got \[(1 \times \frac{4}{5} \times \frac{3}{5} \times \frac{2}{5})(\frac{4}{5} = \frac{96}{625})\]

Answer 4

Sorry I put the parenthesis in the wrong place, but nonethless 96/625

Answer 5

Answer 6

Why is math so hard

Answer 7

Answer 8

The second time he chooses to lick a lollipop, does he still have 5 lollipops to choose from or is it 4?

Answer 9

still thinking
lets put one lollipop aside and then see if we can figure the probability that he picks each one of the other 4

Answer 10

Condition 1)

1st: 5 choices
2nd: 4 choices
3rd: 3 choices
4th: 2 choices
5th: 4 choices

Therefore \[\frac{5 \times 4^2 \times 3 \times 2}{5^5}\]
