What is the probability of flipping a coin twice and it landing on heads exactly one time?
The answer is 1/2 , assuming the coin is fair.
What is the probability of getting 3 girls in a family of 10 children?
The probability of exactly 3 girls in a family of 10 children, assuming equal chance of a boy or girl, is 0.1172. This is a binomial distribution.
The probability Mary will receive an A in a class is 0.61 Assuming independence if she is taking 5 classes this semester calculate the probability she will receive exactly 3 As?
P(3a) = 5c3 ∙(0.61)3∙(0.39)2 = 0.3452... ~ 34.5%

The probability is 2 - 6
What is the probability of getting exactly 2 heads by flipping 3 coins?
The probability is 0.375

What is a business loan?
A computer is programmed to generate a sequence of three digits, where each digit is either 0 or 1, and each of these is equally likely to occur. Construct a sample space that shows all possible three-digit sequences of 0s and 1s and then find the probability that a sequence will contain exactly one 0.

A coin is flipped 3 times what is the probability of 2 tails?
Assuming we want two tails exactly, the possible options to get them are: TTH, THT and HTT. They are three choices out of the eight available, which is a probability of 3/8, 0.375 or 37.5%.
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
What is the probability of getting exactly 2 heads by flipping 3 coins?
The probability is 0.375
What is the probability of tossing exactly 3 tails?
.125
What is the probability of getting 2 heads when you toss three coins?
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.
10 coins are tossed once .The probalilty of getting exactly eight heads is?
The probability of getting 8 heads out of 10 tosses is (10C8)(1/2)^8 (1/2)^2 = 45 / 1024 = 0.0439. It is assumed that the probability of getting a head in a single toss is 1/2. 10C8 = 10 x 9 / 1 x 2 = 45
