Question

Luz speaks Spanish fluently. For every 102 words she speaks, she only mispronounces 6 words. What is the probability the next word she speaks is said correctly?

Answer 1

The probability that the next word she speaks is correct is 16/17, .9412, or 94.12%.

Explanation:

First find the probability of getting a word incorrect, this is done by taking the number of words incorrect and subtracting that from the total. Then taking the difference and putting it over the total.

p(correct)=(102-6)/102

p(correct)=96/102

p(correct)=16/17

p(correct)=0.9412

Therefore the probability that the next word she speaks is correct is 16/17, .9412, or 94.12%.
