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 a head when a biased coin is tossed?

1 Expert Answer The probability of getting a head on any one toss of this coin is 3/4.

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 of flipping 2 heads and 2 tails?

Looking at our sample space, how many different coin toss permutations result in any combination 0f 2 heads and 2 tails? Notice that 6 out of 16 possible outcomes result in a two head/two tail combination.

What is the probability of getting heads 3 times 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 having 3 heads?

1/4
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.

What is the probability of getting 2 heads in 3 coin tosses?

0.5 is the probability of getting 2 Heads in 3 tosses. Exactly 2 heads in 3 Coin Flips The ratio of successful events A = 3 to total number of possible combinations of sample space S = 8 is the probability of 2 heads in 3 coin tosses.

What is the probability of a biased coin having a tail?

Fair coin – heads, fair coin – tails, biased coin – heads, biased coin – tails. Their probabilities each are 1 2 × 1 2 = 1 4, 1 2 × 1 2 = 1 4, 1 2 × 4 5 = 2 5, and 1 2 × 1 5 = 1 10.

What is the probability of a coin being drawn at random?

Any pointers or hints will certainly be appreciated: A box contains 5 fair coins and 5 biased coins. Each biased coin has probability of a head as 4 5. A coin is drawn at random from the box and tossed. Then a second coin is drawn at random from the box (without replacing the first one).

What is the probability of all 3 flips coming up heads?
