What is the probability of tossing 2 heads and 2 tails with a coin tossed 4 times?

When h=head, t=tails
First toss: heads/tails (1h/1t)
Second toss: heads/tails (2h/1h1t*2/2t)
Third toss: heads/tails (3h/2h1t*3/1h2t*3/3t)
Fourth toss: heads/tails (4h/3h1t*4/2h2t*6/1h3t*4/4t)
In short, 1+4+6+4+1=16
Chances of getting 2 heads and 2 tails = 6/16 * 100% = 37.5%

If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
What is the probability of getting tails if a coin is tossed 4 times?
If you look at the as the probability of getting 1 or more tail in 4 coin tosses, you would then calculate the probability of tossing 4 heads in a row and subracting that from 1. The probability fo tossing 4 heads is 1/2 * 1/2 * 1/2 * 1/2 = 1/16. 1 - 1/16 = 15/16.
What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?
50/50
What is the probability of tossing exactly three tails?
well it depends on what you are tossing, if its a coin then no. it can be heads too. it would have to be a great coincidence for it to be all tails, but thats why the word probability comes in meaning that there is more than one outcome
Possible outcomes of tossing a coin?
Heads or tails; each have a probability of 0.5 (assuming a fair coin).
What is the probability of tossing heads then heads and then tails when tossing a coin 3 times?
3 out of 6
If a coin is tossed 3 times what is the probability of 3 heads?
There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.

What is the probability of getting tails twice in a row?
The probability of tossing a coin twice and getting tails both times is 1 in 4, or 25%. If you have already tossed a coin and had it land on tails, the probability that it will land on tails again the next time you toss it is 50%.
What is the probability of a coin tossed 6 times to have 3 heads and 3 tails?
50/50

What is the probability of getting 3 heads and 3 tails if a fair coin is tossed 6 times?
only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125
A coin is flipped 2 times and the number of heads is observed. Find the probability of tossing 2 heads or 2 tails.?
It is 1/2.
What is the probability of tossing a coin and getting an even number?
Zero. Since coins land on Heads or Tails and not numbers.
What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?
The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on
