As there are 3 dice, it is quite easy (and quick) to work out the possible ways a sum of 10 can be made:
If the first die is a 1, the second and third dice could be {3, 6}; {4, 5}; {5, 4}; {6, 3} - 4 possibilities
If the first die is a 2, the second and third dice could be {2, 6}; {3, 5}; ...; {6, 2} - 5 possibilities
If the first die is a 3, the second and third dice could be {1, 6}; {2, 5}; ...; {6, 1} - 6 possibilities
If the first die is a 4, the second and third dice could be {1, 5}; {2, 4}; ...; {5, 1} - 5 possibilities
If the first die is a 5, the second and third dice could be {1, 4}; {2, 3}; ...; {4, 1} - 4 possibilities
If the first die is a 6, the second and third dice could be {1, 3}; {2, 2}; {3, 1} - 3 possibilities
So there are 4 + 5 + 6 + 5 + 4 + 3 = 27 possible ways of getting a sum of 10
With 3 dice there are 6 × 6 × 6 = 216 possible ways of them landing
→ pr(sum 10) = 27/216 = 1/8 = 0.125 = 12.5%
You have more chance with two dice rolled together ! The Probability of throwing a six with one dice is 1/6. The probability of throwing one six with two dice is 2/6 or 1/3. You're twice as likely to score a six if you're throwing two dice.
The probability is 0.5
The probability of getting a perfect score in a three-question true or false quiz is 100% if you studied and retained the subject matter and the questions addressed that subject. If, however, you did not study, and you made pure guesses without any bias towards an answer partially based in your (now rather poor) knowledge, then the probability of getting any one question correct is 50%, so the probability of getting all three questions correct is 50% to the third power, or 12.5%.
The z-score must be 1.87: the probability cannot have that value!
It means that your raw score is four standard deviations below the mean. This will mean different things depending on the context of the question. If you're looking at the probability of a single score occurring in a given distribution (say, a score of 40 in a distribution of scores with a mean of 80 and a std. dev. of 10), then this means that the probability of getting a 40 is very, very low--less than .00002.

P(score>3)=1/6+1/6+1/6=3/6=1/2
If you answer randomly, 1 in 8.

The goal is H-shaped with a net below the crossbar, similar to a soccer goal and rugby goalposts being stuck together. Getting the ball over the bar gives one point and getting the ball into the net gives 3 points. Scoring is mainly done by hitting the ball with the Hurling stick. The ball can be kicked but not be thrown for a score.
no, z score can be negative but a probability is a always positive between 0 and 1.
There are six possible outcomes of rolling a six sided die.However, only two of these (1 and 2) are favorable.So, the probability of rolling less than three is 2/6 = 1/3.
The z-score must be 1.87: the probability cannot have that value!
