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.

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 probability of tossing a numbre less than 3 on a number cube labeled 1 to 6?
The probability of tossing a 1 or 2 on a six sided die is 2 in 6, or 1 in 3.
