28 times out of 50 as a percent is achieved thus
(28/50)*100 = 56%
(The coin would appear to be biased by the way).
20 percent times 120 is 24.
15 percent times 36000 is 5400.
75%0.75 times 100 percent 0.75 * 100%= 75%
600 times 7 percent = 42600 * 7% = 600 * 0.07 = 42
450 times 7.5 percent = 33.75450 * 7.5% = 450 * 0.075 = 33.75
Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.
In 34 or fewer tosses, the answer is 0. In infinitely many tosses, the answer is 1. The answer depends on the number of tosses and, since you have chosen not to share that critical bit of information, i is not possible to give a more useful answer.

Ok if the probability of getting yellow is 9/16 then the prob of getting red is 7/16. If we got red 35 times during the experiment that means the number of tosses was 80. Since 35/n = 7/16 where n = the number of tosses Answer: n = 80 tosses
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.

For 4 coin tosses, there are 16 possible outcomes. Tails on 75% of 4 tosses is 3 times tails, and 1 time heads. This occurs in 4 of those 16 possibilities, so the probability is 4/16 = 1/4 (or 25%). But if the question is 'what is the probability that it's tails at least 75% of the time, then you have to add in the 1 where all 4 are tails, then you have 5/16 (or 31.25%).
Pr(At least one head in 3 tosses) = 1 - Pr(No heads in 3 tosses) = 1 - Pr(3 tails in three tosses) = 1 - [Pr(T)*Pr(T)*Pr(T)] since the three tosses are independent. = 1 - 1/2 * 1/2 *1/2 = 1 - 1/8 = 7/8
Pr(4 turns up at least once in two tosses) = 1 - Pr(4 turns up zero times in two tosses) = 1 - (5/6)*(5/6) = 1 - 25/36 = 11/36
Pr(H at least once in 10 tosses) = 1 - pr(No H in 10 tosses) = 1 - Pr(10 T in 10 tosses) = 1 - (1/2)10 = 1 - 1/1024 = 1023/1024
