Question

There is an 84% chance of pressing the wrong button on a keyboard and thus making a typographical error. Assume these errors occur independently of each other and you type 14 letters

Answer 1

The probability of making a typographical error on a keyboard can be calculated using independent events.

Step-by-step explanation:

The subject of this question is Mathematics.

To find the probability of making a typographical error by pressing the wrong button on a keyboard, we can use the concept of independent events. Since each press is an independent event with a 84% chance of making an error, the probability of making an error for 14 letters can be calculated as follows:

• The probability of making an error for each letter is 84% or 0.84.
• Since the errors occur independently, we can multiply the probabilities together: 0.84 x 0.84 x 0.84 x ... (14 times)

Using a calculator or computer, we can evaluate this expression to find the probability of making a typographical error for 14 letters.
