To explain: The chance of getting a tile with the number 5 on it among 20 tiles with numbers 1 through 20 in 20 random trails.
The probability of getting a tile with the number 5 on it among 20 tiles with numbers 1 through 20 in 20 random trails is 0.3774, so there is a chance to get a 5 once in 20 trails.
Given:
The total number of tiles
The theoretical probability that a tile chosen at random is a 5 is
Formula used:
The probability for x success among n independent trials where probability of each success is p is calculated using binomial probability distribution as shown below
Calculation:
The probability that exactly once a tile with the number 5 is picked in 20 trails is calculated as shown below
The probability that exactly once a tile with the number 5 is picked in 20 trails is 0.3774 (rounded to 4 decimal places).
Interpretation:
The probability that tile with the number 5 is occurred exactly once in 20 trials is 0.3774. Thus it can be said that there is a chance that a tile with the number 5 can be selected once in 20 trials.
