Theoretical probability = 0.5 Experimental probability = 20% more = 0.6 In 50 tosses, that would imply 30 heads.

Judy tosses a coin 4 times. draw a tree diagram showing the possible outcomes.What is the probability of getting at least 2 tails?

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.

6/16

50/50

1.05%.

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

8% of 40 is the same as 0.08 times 40 = 3.2

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

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.

.5*.5*.5=1/8or.125

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

The chance is 50%-50% that it will be heads or tails; this does not change regardless of the number of previous tosses and their results.

The probability is 0.09766%.Each toss has a ½ chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is ½ * ½, and three heads out of three tosses is ½ * ½ * ½. So the exact answer is 0.5^10

The probability of getting heads on three tosses of a coin is 0.125. Each head has a probability of 0.5. Since the events are sequentially unrelated, simply raise 0.5 to the power of the number of tosses (3) and get 0.125, or 1 in 8.

One times one percent is one percent, or 0.01.

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%).

Whenever you use percent in a problem, first convert it to a decimal. 80% is .80 In math, "of" usually means "times." 9An exception is "out of" which means "divided by.") Now, you multiply .80 times 98, and you get 78.4

Before you can show your work on a problem, you have to know how to solve it."10 percent" means "0.1", and "of" means "times".0.1 x 130 = 13

It is: (25.7 over 141) times 100 = 18.227% rounded to three decimal places

It is done by: (0.2-0.1)/0.1 times 100 = 100% change or increase

21.500 times 3 percent = 0.645

14 times 521.43 percent = 73.0002
