What is the probability the number of heads when tossing 3 coins?

3/8
Three of the eight outcomes represent the event of 2 heads (and 1 tail): HHT, HTH, and THH. This event also has a probability of 3/8. Only one of the eight outcomes represents the event of 3 heads, so its probability is 1/8.

What is the probability of getting at least one tail when tossing 3 coins?

Probability of NOT getting a tail in 3 coin toss is (12)3=18 . Probability of getting at least 1 tail in 3 coin toss is 1−18=78 .

What is the probability of tossing a coin 3 times and getting tails each time?

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

What is the sample space when a coin is tossed 3 times?

The sample space of a fair coin flip is {H, T}. 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}.

What is the probability that one tail will occur in a toss?

When we flip a coin there is always a probability to get a head or a tail is 50 percent. Suppose a coin tossed then we get two possible outcomes either a ‘head’ (H) or a ‘tail’ (T), and it is impossible to predict whether the result of a toss will be a ‘head’ or ‘tail’. (i) If the favourable outcome is head (H).

What is the probability of getting exactly 1 tail?

Since there are 4 possible outcomes with one head only, the probability is 4/16 = 1/4. N=3: To get 3 heads, means that one gets only one tail.

What is the probability of tossing 3 tails with 3 coins?

Probability of getting 3 tails in 3 coin flips is 18 .

What is the probability of getting 3 heads or 3 tails?

Problem Answer: The probability of getting either 3 heads or 3 tails is 1/4.

Is tossed 3 times find out the number of possible outcomes?

(a) In a single throw of a coin there are 2 possible outcomes namely Head (H) and Tail (T). So, by the fundamental principle of multiplication, the total number of possible outcomes in 3 tosses =(2×2×2)=23=8. (i) total number of possible outcomes in 4 losses =(2×2×2×2)=24=16.

What is the probability that three tosses of a fair coin will result in 3 heads?

0.125
Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125.

What is the probability of getting two tails?

(ii) getting two tails: Then, E2 = {TT} and, therefore, n(E2) = 1. Therefore, P(getting 2 tails) = P(E2) = n(E2)/n(S) = 1/4.

What is the probability of getting at least one tail when you toss 2 coins?

This states that the probability of the occurrence of two mutually exclusive events is the sum of their individual probabilities. As you can see from the picture, the probability of getting one head and one tail on the toss of two coins is 0.5.
