The probability of picking a distinct set of 3 numbers from 20 is
1/[20!/(3!)(17!)]
= 1/1140
The probability of only picking 3 from 20 is
1/20
The probability is 8/20.
The probability is 11/21.
The probability, in a single random selection, is 1/20 or 0.05
A 1 out of 5 chance, or 20%
The probability of picking a 15 or a 16 from the random set [1-20] is 2 in 20, or 1 in 10, or 0.1.
20 is an integer and not a fraction.
20 is an integer and not a fraction.
0.95 in fraction form is 19/20
It is: 49/20
23/20 = 1.15
0.35 is already a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, it is in the simplest decimal form. Its equivalent, in rational form, is 7/20.
Any integer can be expressed as a fraction in its simplest form by putting it over 1.
