The value of 4800 is 4800 and probability has nothing to do with it.
The probability is 8/20.
No, a probability must needs be a number between 0 and 1.20% might be a probability, though - since that is equivalent to 0.2.
(25-21) / (28-20) = 4/8 =0.5 or 50%
The probability is 20/50 = 0.4
Probability of a spinner of 20 landing on 5 is 1/20.
I think you left off some important information. Perhaps you can supply this information, to obtain assistance. To calculate the probability or the chance of occurrence between two values, we calculate: Pr{a < X < b} = F(b) - F(a) where F(x) = cumulative probability distribution. The distribution requires certain known parameters. In the case of the Normal distribution, the mean and standard deviation are parameters. In your particular case, a = 20 and b = 28.
The probability of picking a distinct set of 3 numbers from 20 is1/[20!/(3!)(17!)]= 1/1140The probability of only picking 3 from 20 is1/20

The probability is 11/21.
The probability, in a single random selection, is 1/20 or 0.05
The value of a random variable that is uniformly distributed between 20 and 100 can be calculated by calculating the sum of numbers from 20 to 100 and dividing it by the difference between 100 and 20. The resulting mean is 58.5.
