What is the probability of rolling a die 120 times and getting 5 or 6?

It is 1 - pr(no 5 nor 6 in 120 rolls)
= 1 - (2/3)120
= 1 - 1.113*1057
which is so close to 1 as to make no difference.
It is 0.99...98887 which starts off with a string of 56 nines.

I rolled the dice 120 times what's the probability of getting a 6?
If you rolled a die 120 times, the probability of getting a 6 is one in six. It does not matter how many times you roll the die - the probability is still one in six - except that the long term mean will approach the theoretical value of 0.166... as the number of trials increases.
What is the probability of getting heads 7 times in 12 tosses of a coin?
99/512, or 19.34%. The nCr formula can be used in this case: 12!/((12-7!)*7!) ---> 95,040/120 ---> 792 792/(2^12) = 99/512

What are the odds of rolling a small straight 12345 with five dice with the rules of yahtzee?
The probability is 120/7776 = 0.0154, approx.
A six sided cube numbered 1 through 6 is rolled 120 timesThe number 4 comes up 19 times what is the theoretical probability of rolling a 4?
Because we are only modeling one event, all six outcomes of the die are equally possible. The probability of rolling a four (or, for that matter, any number) is 1/6, or .166666 repeating. Now, since we are modeling 120 rolls, the theoretical number of outcomes of four (or, again, any number) is 1/6 * 120 = 20 outcomes. The second sentence of the problem is unnecessary.
Why can't 120 percent be a probability of an event?
The probability of an even must be a real number in the range [0, 1]. 120% is outside that range.

The probability of an event is 20 percent How many times should you expect this event to occur in the given number of trials 15 trials 40 trials 75 trials 120 trials?
15 trials: 3 times 40 trials: 8 times 75 trials: 15 times 120 trials: 24 times But don't bet on it.

What is the probability of five books being placed in alphabetical order of their titles if randomly put on a book shelf?
There are 5! (that is, 120) distinct ways to arrange five items. Only 1 of them will have the books in alphabetical order by title. So the probability that it happens by random is 1/120.
