Three fair coins are tossed determine the probability of the following event exactly two coins land on heads?
The sample space is 23 or 8; which can be listed out as: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. There are 2 of the 8 that have exactly 2 heads; so the probability of exactly two coins landing on heads is 2/8 or 1/4.
What is the probability if you flip 3 coins and get three heads?

What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
If four coins are tossed what is the probability of tossing all heads?
The probability is 1/21/21/2*1/2=1/16, or 0.0625 or 6.25%

Coins do not have numbers, there is only the probability of heads or tails.
Four coins tossed what is the probability of tossing all heads?
If they are fair coins, it is 1/16.
Two coins are tossed What is the probability of both coins are heads?
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
If n coins are tossed simultaneously what is the probability that they are all show heads?
