It is 1/2^7 = 1/128.
The probability is 3/4.
(0.5)n
3/8
The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
The probability is 1/16.
The probability of tossing two heads in two coins is 0.25.
1/2 or 50% (1/8 prob of 0H + 3/8 prob of 1H)
Coins do not have numbers, there is only the probability of heads or tails.
1/4 if they are tossed only once.
50/50
If they are fair coins, it is 1/16.
