The probability of a Prime number in a random pick from the numbers 1-49 is 15 in 49, as there are 15 prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43,and 47) in the range of 1 to 49.
Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
There are 15 primes from 1 to 49 (including '1').The probability is (15/49) = 30.612 %(rounded)
Prime numbers from 1 to 15 are: 2 3 5 7 11 and 13 So the probability is: 6/15 or as 2/5
Since 49 is a composite, the answer is 0.
1/10
The chances of picking a number between 2 to 5 is 4/10 if the numbers to be picked from are 1-10. However, if the numbers to be picked from are 1-100, then the probability drops to 4/100.
If they are randomly picked, each 5-number combination is equally likely. If the long-term results of any lottery show that any number or combination is more likely than others, then the game is not honest.
If the winning numbers are picked at random, the probability is 1 in 169911.
There are 8 out of 20 numbers that are prime, so 8/20, or 2/5.
There are 20 numbers in total from 1 to 20. The even numbers in this range are 2, 4, 6, 8, 10, 12, 14, 16, 18, and 20, totaling 10 even numbers. Therefore, the probability of picking an even number is the number of even numbers divided by the total numbers, which is ( \frac{10}{20} = \frac{1}{2} ). Thus, the probability of selecting an even number is 0.5 or 50%.
Pr(Both picked 3) = 1/16Pr(Both picked the same) = 1/4.
