What is the sample space for tossing a coin 4 times?
In counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: HTTT, THTT, TTHT, or TTTH. Each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
What is the sample space for tossing a coin 3 times?
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}.
When a fair coin is tossed 4 times there are 16 possible outcomes?
Complete step by step answer: We know that a coin can give heads or tails that is 2 outcomes. If it is tossed n times then it can give 2n outcomes. Here it is being tossed 4 times it means it will give 24=16 outcomes. So, the total number of outcomes is 16.
When a fair coin is tossed 4 times what is the probability of tossing at least 3 heads?
The answer is 5/16 because in total there are 16 possibilities when tossing a coin 4 times. I.e. 2⋅2⋅2⋅2=24.
What are the possible outcomes when 3 coins are tossed?
When three coins are tossed the total number of possible combinations are 23 = 8. These combinations are HHH, HHT, HTH, THH, TTH, THT, HTT, TTT. The number of combinations which have two heads and one tail are: HHT, HTH, TTH which makes them 3 in number.
What is the probability of flipping 3 heads in a row?
1/8
Answer: If a coin is tossed three times, the likelihood of obtaining three heads in a row is 1/8.
What is the probability of flipping a coin 4 times and getting 4 heads?
This means the probability of landing all 4 heads in 4 tosses is 1 out of the 16. So the answer is 1/16.
How many possible outcomes are there when 4 coins are tossed?
16 possible outcomes
Each coin has two possible outcomes – heads or tails. Therefore, the total number of possible outcomes is: 2×2×2×2=16 possible outcomes.
What is the probability of getting at least one head when three coins are tossed simultaneously?
7/8
(iii) Let E3 denotes the event of getting atleast one head. Hence the required probability is 7/8.
How many outcomes are there if you flip a coin 4 times?
Four Flips Suppose we flip a coin four times. Since each flip can come up heads or tails, there are 16 possible outcomes, tabulated below, grouped by the number of heads in the four flips.
What is the probability of flipping exactly 3 heads when flipping a coin 4 times?
N=3: To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. Thus there are only 4 outcomes which have three heads. The probability is 4/16 = 1/4.
How to find sample space?
The three most common ways to find a sample space are: To List All the Possible Outcomes. Create a Tree-Diagram. Use a Venn Diagram.
How do you find sample space?
The sample space is the set of all possible outcomes of an experiment. Therefore, the sample space can be found by listing all possible outcomes. Example: The experiment consists of flipping two coins. The possible outcomes will be all the pairs head-tail, head-head, tail-tail etc.
What is an example of a sample space?
The concept of a sample space is fundamental to probability theory. It is the set of all possibilities (or possible outcomes) of some uncertain process. For example, the sample space of the process of flipping a coin is a set with 2 elements. Each represents one of the two possible outcomes: “heads” and “tails”.
What are some examples of sample space?
When dealing with any type of probability question, the sample space represents the set or collection of all possible outcomes. In other words, it is a list of every possible result when running the experiment just once. For example, in one roll of a die, a 1, 2, 3, 4, 5, or 6 could come up.
