Answer to Problem 3E
The probability is 0.9.
Explanation of Solution
Given:
The probability distribution is:
Value of X | 0 | 1 | 2 | 3 | 4 |
Probability | 0.1 | 0.2 | 0.3 | 0.3 | 0.1 |
Calculation:
Consider, X be the random variable that shows the number of nonword errors. The at least non-word error could be written as
The probability is computed as:
The probability is 0.9.
b.
To explain: The event
b.
