It is 10C4 = 10!/(6!*4!) = 10*9*8*7/(4*3*2*1) = 210

If a die is rolled and a coin is tossed what is the probablity of obtaining a head and a 5?
1 in 12 chance
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.
How many ways could you get exactly 2 heads when 3 coins are tossed?
3
When a quarter is tossed four times How many times are exactly three tails tossed?
Out of the 16 possible outcomes for a coin tossed four times, 4 of them result in 3 Tails & 1 Head. They are: TTTH, TTHT, THTT, and HTTT.
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.

How many ways you can get exactly one head when a coin tossed 8 times?
8.
How many ways could you get exactly 2 heads when 3 coins are tossed?
3
When a quarter is tossed four times How many times are exactly three tails tossed?
Out of the 16 possible outcomes for a coin tossed four times, 4 of them result in 3 Tails & 1 Head. They are: TTTH, TTHT, THTT, and HTTT.
When a fair coin is tossed twenty times in a row what is the probability that you get exactly fifteen heads?
3/8ths
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
If 3 fair coins are tossed what is the probability of getting exactly 2 tails?
The probability is 3/8 = 0.375
A fair coin is tossed three times find the probability of getting exactly 2 heads?
3 out of 8
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)
