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%
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6

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 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.

In a twenty question true false examination a student must achieve eight correct answers to pass if student answers randomly what is the probability that student will fail?
The probability this student will fail is the same as the probability that some other student will flip a fair coin 20 times and get less than 8 heads, i.e., more than 12 tails. There are 2^20 possible different-looking sequences of 20 coinflips, which we assume all have equal probability. Of those sequences, 1 has no heads at all, 20 have exactly 1 head, 190 have exactly 2 heads, ... and 77520 have exactly 7 heads. So we sum up all those possible ways to fail and we get ... ... ... I'm assuming that the student answers randomly, flipping a fair (50:50) coin on each question to choose "true" or "false". In that special case, it doesn't matter how many of those twenty questions are true or how many are false. (If the student answers randomly by flipping an unfair coin, say a 25:75 coin, then it does matter how many of those questions are true -- I'll let you figure that one out).
