# When we toss 3 coins What is the probability?

## When we toss 3 coins What is the probability?

Solution: When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E1 denotes the event of getting all tails. Hence the required probability is ⅛.

How do you sample space for 3 coins?

The sample space of a sequence of three fair coin flips is all 23 possible sequences of outcomes: {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}. The sample space of a sequence of five fair coin flips in which at least four flips are heads is {HHHHH,HHHHT,HHHTH,HHTHH,HTHHH,THHHH}.

### When flipping 3 coins What is the probability of getting 3 tails?

1/8
Answer: The probability of flipping a coin three times and getting 3 tails is 1/8.

How to calculate the probability of tossing three coins?

Important Formulae 1 The possible outcomes of tossing 3 coins are { (HHT), or (TTH) or (HHH) or (THT) or (THH) or (HTH) or (HTT) or (TTT)} 2 The total no of possible outcomes = 8 3 The probability of getting at least one head = number of possibilities of heads as outcome/total no of possibilities = 3/8

## What are the outcomes of a coin toss?

When 3 coins are tossed, the possible outcomes can be {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. Thus, total number of possible outcomes = 8 Getting at least 2 tails includes {HTT, THT, TTH, TTT} outcomes.

What is the formula for the coin toss?

Let us learn more about coin toss probability formula. Probability is the measurement of chances – likelihood that an event will occur. If the probability of an event is high, it is more likely that the event will happen. It is measured between 0 and 1, inclusive. So if an event is unlikely to occur, its probability is 0.

### What is the probability of heads and tails on a coin?

If we toss a coin, assuming that the coin is fair, then heads and tails are equally likely to appear. As these are the only two possible outcomes, each has probability of 1/2 or 50 percent.
