What is the probability of obtaining a number less than 5 when a single fair die is tossed?

How many numbers less than 5 = 4 (1, 2, 3, 4)
How many sides on a fair number cube = 6
Put 4 over 6 = 4/6
Simplify:
4 ÷ 2 = 2
6 ÷ 2 = 3
Making the answer 2/3.

When two coins are tossed simultaneously what is the probability of obtaining at most one head?
The probability is 3/4.
What is the probability of obtaining tails or a six?
The answer depends on the experiment: how many coins are tossed, how often, how many dice are rolled, how often.
If a die is tossed once probability of it landing on a 6?
Since there are 6 possible outcomes, and you want the probability of obtaining one of the outcomes (in your case 6), the probability of it landing on a 6 is 1/6.
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
What is the probability that the die tossed will land on a number that is smaller than 5?
The probability that the die tossed will land on a number that is smaller than 5 is 4/6 or 2/3. Smaller than 5 is 1 - 4 and 6 is the sample space.
What is probability of obtaining a number different from 11 when a single fair die is tossed?
A single fair die has the numbers 1 to 6, so when a single fair die is tossed the probability of obtaining a number different than 11 is: P(x diff than11) = 1.
What is probability of obtaining a number different from 12 when a single fair die is tossed?
assuming we are talking about standard dice here (six sided, numbered 1-6) then the probability of obtaining a result other than 12 when a single die is tossed is 100%. There is no way to roll a 12 after 1 toss of 1 die, therefore the chance of getting anything other than 12 is guaranteed

An ordinary die is tossed four times what is the probability of obtaining a number greater than 4 at least once?
1 - (2/3)4 = 1 - 16/81 = 65/81 ≈ 80.25%
Probability is the what that something will or will not occur?
Probability is the likelihood that something will occur. If you subtract it from 1, we get the likelihood (or probability) that it will not occur. If a coin is tossed and rolls heads 6 times, the (empirical) probability of obtaining a head is 6/10 or .6. 1-.6 =.4 is the empirical probability (or likelihood) of not getting a head.
What is the probability that the die tossed will land on a number that is smaller than 5?
The probability that the die tossed will land on a number that is smaller than 5 is 4/6 or 2/3. Smaller than 5 is 1 - 4 and 6 is the sample space.
If nine fair coins are tossed what is the probability of obtaining at least one head and at least one tail using the complement formula?
255/256 (complement formula)
Three dice are tossed what is the probability that the same number appears on exactly two of the three dice?
The probability is 90/216 = 5/12
What is the probability of getting 2 heads if a coin is tossed thrice?
(1/2)^3 = 1/8th Since the initial probability (assuming independence) of getting a head in a single toss is one half (1/2) we just cube this probability because of the number of events we are performing. So if you were to try to calculate the probability of a coin being tossed 6 times it would be one half to the 6th power which is 1/64.
