The probability of a combination of independent outcomes is equal to the product of the individual probabilities. The probability of any particular dime coming up heads is 1 in 2 or 1/2 (or 1:2 or .5 or 50%)
The probability of ALL three dimes coming up heads is...
1/2 * 1/2 * 1/2 = 1/8

the probability of show a head is 1/2. But there are 3 dimes, so the probability of getting 3 heads is:
P = 1/2 * 1/2 * 1/2 = 1/8

P( 3 h's ) = P(h) * P(h) *P(h)
= 1/2 * 1/2 * 1/2
=1/8

You have a 50% chance each time.
So 1/2*1/2*1/2=1/8.
You have a 12.5% chance.

you have 3 dimes, there for there is 4 possible outcomes.
3 heads
2heads1tails
2tails1head
3 tails.
so the answer is 1 out of 4 or 25%

there are 4 possibilities
3 heads
3 tails
2 heads and 1 tail
1 head and 2 tails
so I'd say 1 out of 4
not mathematical
