If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2, the probability is 3/8, or 37.5%. There are 3 independent coin tosses, each of which is equally likely to come up heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH, etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2 heads, so the probability of that is 3/8.
The experimental probability of a coin landing on heads is 7/ 12. if the coin landed on tails 30 timefind the number of tosses?
1/2 or 5/10
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
The probability of tossing two heads in two coins is 0.25.
To find the probability of getting exactly two heads in four coin tosses, we can use the binomial probability formula. The number of ways to choose 2 heads from 4 tosses is given by the binomial coefficient ( \binom{4}{2} = 6 ). The probability of getting heads on each toss is ( \frac{1}{2} ), so the probability of getting exactly 2 heads is ( \binom{4}{2} \times \left(\frac{1}{2}\right)^2 \times \left(\frac{1}{2}\right)^2 = 6 \times \frac{1}{16} = \frac{6}{16} = \frac{3}{8} ). Thus, the probability of getting exactly two heads is ( \frac{3}{8} ).
The probability is 0, since there will be some 3-tosses in which you get 0, 1 or 3 heads. So not all 3-tosses will give 2 heads.
The probability is 1 out of 5
1/4
The conditional probability is 1/4.
It is 3/8.
2 out of 3 i think
0.53 = 0.125.
With 3 coin tosses, the possible outcomes are: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT There are 8 possible outcomes and 3 of them have 2 heads. Thus: probability = 3/8 (= 0.375)
In two tosses: 1/4.
It is 0.3438
With 5 coin tosses there are 32 possible outcomes. 10 of these have exactly 2 heads, and 26 of these have 2 or more heads.For exactly two coins are heads: 10/32 = 31.25%For two or more heads: 26/32 = 81.25%
