This is a binomial probability distribution The probability of exactly 2 heads in 50 coin tosses of a fair coin is 1.08801856E-12. If you want to solve this for how many times 50 coin tosses it would take to equal 1 time for it to occur, take the reciprocal, which yields you would have to make 9.191019648E11 tosses of 50 times to get exactly 2 heads (this number is 919,101,964,800 or 919 billion times). If you assume 5 min for 50 tosses and 24 hr/day tossing the coin, it would take 8,743,360 years. That is the statistical analysis. As an engineer, looking at the above analysis, I would say it is almost impossible flipping the coin 50 times to get exactly 2 heads or I would not expect 2 heads on 50 coin tosses. So, to answer your question specifically, I would say none.

If you toss three coins 360 times how many times can you expect the coins to have three heads showing?

around 45


If you toss 2 coins simultaneously 400 times would you expect the deviation to be greate or less than it was in tossing them 40 times?

Less. The more times the coin is tossed, the more likely it will reflect the actual odds of .5 heads and .5 tails.


Two coins are going to be tossed 780 times Predict the number of times 2 heads will be tossed?

Half the time they will be the same, half the time they will be different. Half of the time that they're the same they will be heads, half the time they are the same they will be tails. It's your homework, YOU figure it out. The way I figure it. There are four options: 1) heads / heads 2) heads / tails 3) tails / heads 4) tails / tails By process of chance, one out of four times both coins will be heads/heads. Therefore 780/4 = 195 times.


A coin is tossed 100 times how many times would you expect to get heads?

The probability of a heads is 1/2. The expected value of independent events is the number of runs times the probability of the desired result. So: 100*(1/2) = 50 heads


How many orders can heads and tails be tossed when a coin is tossed 3 times?

Eight.


What are the odds if a coin is tossed 3 times and the out come is heads?

The answer depends on "the outcome is heads HOW MANY TIMES!"


If you toss three coins 10000 times how many times would you expect that exactly 2 heads appear?

The expected number is 3750.


How many combinations of one head and one tail would you expect if two coins were tossed together forty times?

The theoretical probability of HT or TH when two coins are tossed is 1/2 . (All possible outcomes are HH,TT,HT,TH). This means that when we run the experiment repeatedly we expect to get the desired result 1/2 of the time. Since you intend to toss the coins 40 times, 20 are expected.


What is the probability that I'll get heads on the next toss if I tossed a coin fifteen times and got heads twelve?

The odds are 50/50. A tossed coin does not have a memory.


A coin is tossed 60 times It landed on heads 21 times what is the experimental probability of getting heads?

1/2


When three coins are tossed how many times out of 100 would you expect the result to be either three heads or three tails?

Each coin has 2 outcomes. Either being heads or tails. Take the outcome of each coin to the root of the number of coins. (1/2)^3 = .125 = 12.5% or a 1 in 8 chance. Take .125 and times it by 100 to get the probability out off 100 times. .125 x 100 = .125 which = 12.5%= 1 in 8 chance


What is the probability of a coin tossed two times to get heads?

It is 3/4
