What is the probability that the random variable has a value less than 5?
That depends on the rules that define the random variable.
What is the probability of getting less than 10 when you roll a dice?
A die normally has six sides with the numbers 1 to 6 on them, so any roll will be less than 10 and thus the probability of getting less than 10 with a die is 1. With two normal dice, the sum of the digits on the dice added together ranges from 2 to 12 and the probability of getting less than 10 is the same as 1 minus the probability of getting 10 or more. There are 36 ways the two dice can fall and 10 can be achieved in 3 ways (4&6, 5&5, 6&4), 11 can be achieved in 2 ways (5&6, 6&5) and 12 in 1 way (6&6). Thus the probability of getting 10 or more with 2 dice is (3+2+1)/36 = 6/36 = 1/6 So the probability of getting less than 10 is 1-1/6 = 5/6
What does Pr mean in math?
In all likelihood, it stands for Probability. For example, Pr(X < 3) is a way of writing "Probability that a random variable, X, takes a value less than 3".
What is the pobability of randomly selecting a month with 31 days?
The probability is 7:12... There are five months with less than 31 days, so the probability of selecting a month with exactly 31 days is 7 out of 12.
What is the probability of rolling a number less than 4 on a 6-sided number cube labeled 1-6?
3 out of 6, or 50%
What is the probability of obtaining a number less than three at the throw of a dice?
There are 6 values, 1 - 6, on the die. Less than 3 is a 1 or 2 roll. So, probability of less than 3 is 2/6 or 1/3 or 33.33%.
The probability of obtaining a sum greater 8 or less than 6?
The answer depends on what the experiment consists of. Since that is not specified, there can be no sensible answer.
What is the probability of obtaining a sum of at least 6when rolling a pair of dice?
The best way to do this is to note that this is 1 minus the probability of obtaining a sum less than 6. The probability of obtaining a 2 is 1/36 (both dice get 1) The probability of obtaining a 3 is 1/18 (one dice gets 1, the other gets 2, or the other way around) The probability of obtaining a 4 is 1/12 (both dice get 2, or one dice gets 1 and the other 3, or the other way around) The probability of obtaining a 5 is 1/9 (one dice gets 2 and the other 3, or the other way around, or one dice gets 1 and the other 4, or the other way around) Adding these probabilities up gives 5/18. 1 minus this is 13/18 Thus the probability of obtaining a sum of at least 6 when rolling a pair of dice is 13/18.
What is the probability that the number rolled will be less than 6?
The probability of rolling a number less than 6 on a die would be 5/6.
When probability is less then 0 what happen?
Probability can not be less than 0 or greater than 1. A probability of 0 means there is no possibility whatsoever of an event occurring. A probability of 1 means that the event is guaranteed to occur no matter what.
Why cannot a probability not be less than 0?
0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.
Can a probability be more than 1 or less than 0?
No. A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1. 0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.
What is the probability of rolling a pair of dice and obtaining a total score greater than 9?
It is 1/12.
What is the probability of getting less than 7 on a standard 6 sided die?
The probability is 1 as all values on a die are less than 7.
Can the value of probability be less than zero?
No. Probability must be between 0 and 1.
What is the probability of rolling a number less than 1?
The probability of rolling a number less than 1 on a standard 6-sided die is zero. It will not happen.
What is the probability of rolling a number less than 3 and greater than 4 with one roll of a number cube?
The probability is zero. No number can be less than 3 and greater than 4.
