How many outcomes are possible if a coin is tossed 3 times?
eight possible outcome
The number of different outcomes when three coins are tossed is 2 × 2 × 2 = 8. All eight possible outcome are HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT.
What is the probability of flipping a coin three times and getting the same result every time?
Three flips of a fair coin Suppose you have a fair coin: this means it has a 50\% chance of landing heads up and a 50\% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5\%.
When a coin is tossed 3 times what is the probability of getting at least one head?
7/8
Summary: A coin is tossed 3 times. The probability of getting at least one head is 7/8.
What is the probability of tossing 3 coins at random?
Hence the required probability is 3/8. Example 2: In an experiment, three coins are tossed simultaneously at random 250 times. It was found that three heads appeared 70 times, two heads appeared 55 times, one head appeared 75 times and no head appeared 50 times. find the probability of:
What is the probability that a fair coin comes up tails?
The probability of A is equal to the probability of (1 – not A). If A is at least one head, then not A is less than 1 head. And the only option for less than 1 head is no heads. Getting no heads is the same as getting all tails. The probability that a fair coin comes up tails is 1/2.
When 3 unbiased coins are tossed once what are the possible outcomes?
When 3 unbiased coins are tossed once. When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E 1 denotes the event of getting all tails. Hence the required probability is ⅛. (ii) Let E 2 denotes the event of getting two heads.
What is the probability of getting 3 heads on a coin?
The probability of getting 3 heads when you toss a “fair” coin three times is (as others have said) 1 in 8, or 12.5\%. However, that isn’t the question you asked. If you toss a coin exactly three times, there are 8 equally likely outcomes, and only one of them contains 3 consecutive heads. So the probability is 1 in 8.
