What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?
The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on
If two dice are rolled what is the probability of getting s sum less than 3?
The only number less than 3 that you can get with two dice is 2. The probability of getting a 2 is 1/36.The only number less than 3 that you can get with two dice is 2.

The probability of getting a 2 is 1/36.The only number less than 3 that you can get with two dice is 2. The probability of getting a 2 is 1/36.
What is the probability of rolling a 3 with a pair of dice?
On a standard pair of six-sided dice, there are two ways to roll a "3"; i.e., a "1" and a "2" or a "2" and a "1". There are 36 possible outcomes. Therefore, the probability of rolling exactly 3 is 2/36, which equals 1/18. The probability of rolling 3 or higher is 35/36. The probability of rolling 3 or lower is 3/36, which is 1/12.
What is the probability that a multiple of 2 is also a multiple of 3?
It is 1/3.It is 1/3.It is 1/3.It is 1/3.
What is the formula used to calculate the probability of arranging 1 to n in the correct order?
There are n! = 1*2*3*...*n possible orders and out of these, only one is correct. So the probability is 1/n!There are n! = 1*2*3*...*n possible orders and out of these, only one is correct. So the probability is 1/n!There are n! = 1*2*3*...*n possible orders and out of these, only one is correct. So the probability is 1/n!There are n! = 1*2*3*...*n possible orders and out of these, only one is correct. So the probability is 1/n!
You spin a spinner two times find the probability that the spinner stops on 3 then 1?
The probability that a spinner with N sides stops on 2 particular numbers in two spins in 1 in N2. It does not matter what the two numbers are, since the two spins are sequentially unrelated.
What the probability of rolling a 6 sided die and getting a 4 or a number divisible by 3?
If the die is fair then for a single roll, the probability is 1/2.
What is the probability of having 3 baby girls in a row?
Assuming that the probability of having a baby girl is 1/2 and that of having a baby boy is 1/2, the probability of having 3 baby girls in a row is (1/2)(1/2)(1/2)=1/8.
What is the probability of rolling a 3 and flipping a head?
probability of rolling a 3 = 1/6 probability of flipping a head = 1/2 therefore, overall = 1/12
What is the theoreical probability for one roll on a dice of a probability of 1 or 3 or 6?
It is 1/2
What is the probability of getting exactly 3 heads if a fair coin is tossed 8 times?
The probability to get heads once is 1/2 as the coin is fair The probability to get heads twice is 1/2x1/2 The probability to get heads three times is 1/2x1/2x1/2 The probability to get tails once is 1/2 The probability to get tails 5 times is (1/2)5 So the probability to get 3 heads when the coin is tossed 8 times is (1/2)3(1/2)5=(1/2)8 = 1/256 If you read carefully you'll understand that 3 heads and 5 tails has the same probability than any other outcome = 1/256 As the coin is fair, each side has the same probability to appear So the probability to get 3 heads and 5 tails is the same as getting for instance 8 heads or 8 tails or 1 tails and 7 heads, and so on

What is the addition rule of probability?
The addition rule of probability states that the probability that one or the other will happen is the probability of one plus the probability of the other. This rule only applies to mutually exclusive events. For example, the probability that a dice roll will be a 3 is 1/6. The probability that the dice roll will be even is 1/2. These are mutually exclusive events as the dice cannot be both 3 and even. Thus the probability of the dice roll coming up either a 3, or even, is 1/2 + 1/6 = 2/3.
What is the probability of rolling a 2 and then a 3 with 6-sised cubes?
The probability of rolling a 2 on the first roll is 1 in 6. The probability of rolling a 3 on the second roll is 1 in 6. However, the probability of rolling a 2 on the first roll and 3 on the second roll before you roll at all is 1/6 x 1/6 = 1 in 36.
What is the probability of rolling a number less than 5 and a head when rolling a die and then tossing a coin?
The probability of rolling a number less than 5; which is a 4, 3, 2, or 1 is 4/6 or 2/3. The probability of tossing a head is 1/2. So, the probability of a roll less than 5 and a head is 2/3*1/2 or 1/3 or 0.333. 4/12
