Total number of possible selections = 20
Number of possible successes = 4 (selection of 5, 10, 15, or 20)
Probability of success = 4/20 = 20%

There are 10 boys and 12 girls in a class if one student is selected at random from the class what is the probability it is a girl?
The probability is the number of girls divided by the number of students, so 12/22, or 6/11

What is the mean number of leaking tanks in such samples of 15?
It is 15 times the probability of a randomly selected tank being leaky.
What is the probability that one randomly-selected person in America will know another randomly-selected person in America?
There is not enough information about the the distribution of the number of people known by each individual - nor the averages. It is therefore no possible to give an answer any more precise than "the probability will be infinitesimally small".
A two-digit whole number is randomly selected What is the probability that it is an odd multiple of 3?
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
What is the probability of hitting even number?
In the list of all integers from negative infinity to positive infinity, there is a 50% chance that a randomly selected integer will be even.
There are an equal number of pennies nickels dimes and quarters in a bag What is the probability that the combined value of the four coins randomly selected with replacement will be 41?
1/35 or 2.86%
What is the probability that the number 23 will be randomly picked out of 100?
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.
Why the probability is have a specified chance to be selected and why the non probability does not have an equal of being selected?
Probability is the number of occurrences of a specific event divided by the total number of possible events. Suppose you took a multiple choice test with 4 possible answer's A, B, C, D. Only 1 of the 4 choices is correct; so the probability of correct is 1/4 and the probability of incorrect is 3/4. Most of the time the two probabilities will not be the same.
Explain what a random number is?
That means that a number is selected randomly from a certain set. For example, if you throw a die, you can randomly get any of the integers from 1 to 6. It is random, because you don't know the result in advance.That means that a number is selected randomly from a certain set.

What is the probability of a prime number being picked randomly from the number 49?
Since 49 is a composite, the answer is 0.
A group of preschool children of 8 girls and 5 boys if she randomly selects on child to be first in line with e being the event that the one selected is a girl what is the probability of event e?
The probability of event e would be the number of girls, 8, divided by the total number of children, 13; or 8/13 or 0.615385.
