What is the probability that either two heads or three heads will be thrown if six coins are tossed at once?

Further getting 2 heads or 3 heads in the toss of 6 coins together are mutually exclusive events. Therefore required probability = (15/64) + (20/64) = 35/64.

What is the probability of getting exactly 2 heads in 6 tosses of a coin?

Taking, n = 6 and r = 2; we can calculate probability of getting exactly two heads in six tosses = (6C2) * [(1 / 2)^2] * [(1 / 2)^(6 – 2)] = (15 / 64) = 0.234375. = 0.890625.

What is the probability of getting exactly 2 heads in 72 hours of a fair coin?

A) The probability of 2 heads is 6/16 = 3/8 = 37.5\%. To find at least two heads, you will need to add on the probability of 3 heads and also 4 heads. to your answer for exactly two heads.

What is the probability of getting 3 heads in 6 tosses?

The number of outcomes with exactly 3 heads is given by (63) because we essentially want to know how many different ways we can take exactly 3 things from a total of 6 things. The value of this is 20. So the answer is 20/64=5/16.

What is the probability of getting 3 heads in tossing 3 coins?

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 one head when 3 coins are tossed?

The number of outcomes from tossing three coins is 8 (HHH,HHT,HTH,HTT,THH,THT,TTH and TTT). Of these outcomes, three qualify as having only one head, HTT,THT and TTH. Therefore the probability of getting exactly 1 head when three coins are tossed (simultaneously or not) is 3/8.

What is the probability of getting exactly 3 heads?

Answer: If you flip a coin 3 times the probability of getting 3 heads is 0.125. When you flip a coin 3 times, then all the possibe 8 outcomes are HHH, THH, HTH, HHT, TTH, THT, HTT, TTT.

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

Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.

What is the probability of obtaining 3 heads in four flips of a fair coin?

So because you are interested in 4 outcomes out of the 16 possible outcomes, so the probability of getting 3 heads out of four flips is 4/16 or 1/4 or 0.25.

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 that the coin is flipped 6 times?

When a certain coin is flipped, the probability of heads is 0.5. If the coin is flipped 6 times, what is the probability that there are exactly 3 heads? The answer is 5 16.

What is the probability of a sequence having exactly three heads?

It is true that each sequence of heads and tails is equally likely to occur – with probability 1 64, in this case. However, the number of those sequences having exactly three heads is not 32, but ( 6 3) = 20, which leads to the correct answer of 5 16. They are two completely different things.

What is the probability that heads and tails are equally likely?

It is true that each sequence of heads and tails is equally likely to occur – with probability \\frac1 {64}, in this case. However, the number of those sequences having exactly three heads is not 32, but \\binom63=20, which leads to the correct answer of \\frac5 {16}.
