What is the probability of flipping three coins with at least two heads?
1/2
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.
What is the probability of getting at least one head on three coin flips?
87.5\%
If you flip a coin three times the chance of getting at least one head is 87.5\%.
What are the chances of flipping a coin 3 times are getting at least two tails?
Listing the outcomes (H being heads and T being tails… HHH, HHT, HTH, HTT, THH, THT, TTH, TTT), it’s clear that 1/2 the outcomes result in at least 2 tails.
What is the probability of flipping a coin 3 times and having it land heads on the first two flips and tails on the third?
Example 1. 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\%.
How many outcomes are possible if you flip a coin 3 times?
eight possible outcomes
There are eight possible outcomes of tossing the coin three times, if we keep track of what happened on each toss separately. In three of those eight outcomes (the outcomes labeled 2, 3, and 5), there are exactly two heads.
How many outcomes are there if you flip 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}.
How many outcomes are there with 3 coins?
What is the probability of getting 3 heads when you toss 3 coins at the same time?
0.125
Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125.
What is the probability of 3 tosses of a coin?
When three fair coins are tossed there is a chance of occuring eight combinations. Hence the probability is 1/8. Each outcome of each flip of a fair coin has a probability of 0.5. The probability of three tosses – three independent samples – will be the product of the probability of each of the tosses.
What is the probability of each outcome of a coin flip?
Gain a global economic perspective to help you make informed business decisions. When three fair coins are tossed there is a chance of occuring eight combinations. Hence the probability is 1/8. Each outcome of each flip of a fair coin has a probability of 0.5.
How many tails can you get from flipping 3 coins?
When you flip 3 coins, you either get a head or a tail. So getting 2 tails and 1 heads is exactly the same event as getting exactly two tails. Thus, as you noted in the last part of your question, the answer is 3 8. Thanks for contributing an answer to Mathematics Stack Exchange!
What is the probability of rolling a coin and getting heads?
Assuming that the coin is ‘fair’ (i.e. a regular coin), the classical interpretation is that the probability of getting heads is exactly 0.5. Again, assuming fair die, the probability of getting any value when rolling is uniformly distributed, so 1/6 for any given value.
