Here we will learn how to find the probability of tossing two coins. Let us take the experiment of tossing two coins simultaneously:. When we toss two coins simultaneously then the possible of outcomes are: (two heads) or (one head and one tail) or (two tails) i.e., in short (H, H) or (H, T) or (T, T) respectively; where H is denoted for head and T is denoted for tail.What is the highest lower bound one can give for the probability of getting exactly one head? If they had been fully independent then I believe the answer is $1/e$ . pr.probability
The events are "head on the first" and "head on the second." The two events are independent because the outcome of the second coin toss does not depend on the outcome of the first coin toss. A pet store has 12 puppies, including 5 poodles, 5 terriers, and 2 retrievers.

The probability of getting exactly two heads when three fair coins are thrown simultaneously is $3/8$. Each coin has a probability of $1/2$ for being a head, or for being a tail, and there are three coins that could be the head. An observer not being able to identify the coins does not change that.

In the experiment of tossing a fair coin 3 times, the sample space is made of thefollowing 8 equiprobable events: S = {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}.The events that at least have one head are 7. So the probability of getting at leastone head on three tosses is: P(at least one H) = 7/8 = 0.875 = 87.5% Let S= {HH,HT,TH,TT} and assume the simple events each have probability 1/4. Then HT means head on the first toss and tails on the second. Since 1 head occurs for simple events HT and TH, A= {HT,TH} we get P (1 head) = 2/4=1/2. Solution 2: Nov 17, 2018 · However, when it comes to writing a probability of a flipping coin, it is written between 0 and 1. It means when you flip a coin, it will land on either heads or tails.

The probability of getting 'tails' when you toss a coin is a 1 in 2 chance, or 1/2. Probabilities can also be shown as decimals or percentages. A probability of 1/2 can also be shown as 0.5 or 50% When there is no reason to expect the happening of one event in preference to the other, then the events are known equally likely events.
