Okay, all you math people. What are the odds?

Question

An individual has three coins randomly placed down on a surface.What are the odds all three will be tails after flipping two random coins three times each? I hope this makes sense! :)

Answer 1

1/8



ok thanks

Answer 2

It does NOT matter how may times you toss the coins before the final toss. Each coin tossed has a 50-50 chance of being tails. So, your odds are 1 in 4 provided the untossed coin is tails. If on the last toss, the untossed is heads, the odds are 0. I am assuming you do not look at the state of each coin, but rather pick a pair and toss each. If the untossed coin was tossed on a previous round, then the odds change to 1 in 8

2 coins with 1 already tails
HH
HT
TH
TT.

Final toss assuming all coins have been tossed at least one time can have only the following results, of which only 1 of the 8 is a winner:

HHH
HHT
HTH
HTT
THH
THT
TTH
TTT

Remember, like a lottery number, the number of times it came up tails previously has NO effect on the next toss. Odds of a coin coming up tails is 50-50, 1 in 2 regardless of history. The same goes for dice with the odds of any given side coming up are 1 in 6, unless of course, the dice are loaded...

Answer 3

The amount of flipping doesn't matter because the chances of heard or tails is equal. So it is just the chance that all 3 will be tails which is 1 in 8.

Answer 4

1:8

Answer 5

The odds are 7 to 1, the "chance" is 1 in 8. the Probability is 0.125 or 12.5 %

Answer 6

each of the three has a 50% chance of being tails, so just multiply (.50)(.50)(.50) to get the answer

Answer 7

I believe it's one in 8. 2x2x2.

Answer 8

1 in 8



Hope this helps!

Answer 9

p=12.5%
