The probability of selecting a 17 (or any number for that matter) is 1/20 or .05 or 5%.
2 numbers. few probabilities. Lets see. Number 1 probability: if your given numbers are this for example, 2 and 7. What is the probability of picking out 7? the Numerator is how many of that number is in the group. They are asking for 7? so how many 7's are in the group? 1. Then the denominator is how many numbers are in the group. There are 2 numbers in the group. so the probability of picking out a 7 would be 1/2. get it? if there were two 7's, then the probability would be 2/2 or 1. I hope I helped.
yes.
There are 90 two-digit numbers from 10 to 99. Of those, 6 are perfect squares (16, 25, 36, 49, 64, and 81) and 2 are perfect cubes (27 and 64). Each perfect square or root has a probability of 1 in 90 in being drawn.
Algebraic expressions is a mathematical phrase that contains operations numbers or variables.
it depends on how many numbers are on the number cube. if it only goes to 6, then the probability is 1/6. if it goes to 8 then the probability is 2/8. and so on and so on...
The probability of getting two prime numbers when two numbers are selected at random and without replacement, from 1 to 10 is 2/15.
The answer depends on how many numbers are selected.The answer depends on how many numbers are selected.The answer depends on how many numbers are selected.The answer depends on how many numbers are selected.
The event space comprises the numbers 10 to 99, 90 such numbers. The favourable events are 15, 21, 27, ... , 99. There are 15 such numbers. So the probability is 15/90 = 1/6
It is called probability. All numbers have an equal opportunity of being selected and if they run the lottery say for 100 billion times they all will probably be selected.

Any normal die contains three numbers that are less than 4 so the answer must be 1.
53 - 1 or 1 chance in 54 or 0.0185 or 1.85%
There are 10 numbers {1, 2, ..., 10} The solution set contains {4, 5, ...,10} - 7 numbers in total → probability = number of successful tries/total number of tries = 7/10 = 0.7
50%, or 1 out of 2. There are 12 numbers, 6 even and 6 odd, so they have equal chance of being odd or even if one is selected
What is the probability of rolling an even with one roll of a numbers cube.
no they are not
The probability is 17C4 = 2380
