What is the probability that three coin flips will have at least one head?
Pr(3 flips at least one H) = 1 - Pr(3 flips, NO heads) = 1 - Pr(3 flips, TTT) = 1 - (1/2)3 = 1 - 1/8 = 7/8
What is the theoretical probability of getting two tails?
The probability of getting two tails is 1/4. The probability of something happening is the answer to the question, "What fraction of the time will this happen?" It is the number of ways it can happen, out of all the different things that can happen. With two coin flips, these are all the things that can happen H H H T T H T T There is one way in which you can get two tails, out of four possible things that can happen. One out of four, or 1/4.
What is the probability of flipping a coin a tail on the first and a head on the second or a head on the first and a tail on the second?
Two flips can have four possible results:T - TT - HH - TH - HThe question defines 'success' as either H-T or T-H.Two successes out of four possibilities = probability of 2/4 = 1/2 = 50% .

How do you find the sample space of an experiment where you flip a coin 6 times and note the number of heads?
The sample space consists of all the possible outcomes. A flip of a coin has 2 outcomes, H,T. The total number of outcomes for 6 flips are 26 or 64.
What is the probability of getting at least 2 heads in three flips of a fair coin?
In three flips of a fair coin, there are a total of 8 possible outcomes: T, T, T; T, T, H; T, H, T; T, H, H; H, H, H; H, H, T; H, T, H; H, T, T Of the possible outcomes, four of them (half) contain at least two heads, as can be seen by inspection. Note: In flipping a coin, there are two possible outcomes at each flipping event. The number of possible outcomes expands as a function of the number of times the coin is flipped. One flip, two possible outcomes. Two flips, four possible outcomes. Three flips, eight possible outcomes. Four flips, sixteen possible outcomes. It appears that the number of possible outcomes is a power of the number of possible outcomes, which is two. 21 = 2, 22 = 4, 23 = 8, 24 = 16, .... Looks like a pattern developing there. Welcome to this variant of permutations.

A fair coin is continually flipped What is the probability that the first four flips are a. H-H-H-H b. T-H-H-H c. what is the probability that the pattern T-H-H-H occurs before the pattern.?
a) 1/16b) 1/16c) 1/256 [this answer was given, but it is unclear what part-c is even asking: The pattern occurs before what pattern? There are many variables which are unspecified and would affect the outcome.]
Which tree diagram shows all the possible outcomes for 2 coin flips?
The tree in which the first set of branches are H and T and then, from each of those nodes, there is a pair of branches which are H and T.

What does pH indicator?
p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH
What is the pH of solution with H plus 2.310?
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636

Write the equation for determining pH?
pH = -log[H+], where [H+] is the hydrogen ion concentration in moles per liter.
How to calculate pH of 1N HCl solution?
The pH of a 1N HCl solution can be calculated using the formula pH = -log[H+], where [H+] is the concentration of H+ ions in the solution. For a 1N solution of HCl, the concentration of H+ ions will be 1M, so the pH will be -log(1) = 0.
