Question

Claudia finds that the experimental probability of her cat waking her between 5:00 A.M. and 6:00 A.M. is 0.811. About what percent of the time does Claudia’s cat not wake her between 5:00 A.M. and 6:00 A.M.?

a) 8.11%
b) 19%
c) 81.1%
d) 100%

Answer 1

Claudia's cat does not wake her between 5:00 A.M. and 6:00 A.M. about 18.9% of the time, which is approximately 19%.

Step-by-step explanation:

The question asks about the experimental probability of Claudia's cat waking her up between 5:00 A.M. and 6:00 A.M. and is given as 0.811. To find the percentage of the time the cat does not wake her, we need to subtract this probability from 1. Since 1 represents the whole or 100%, subtracting 0.811 (or 81.1%) from 1 gives us 0.189 or 18.9%. Therefore, the cat does not wake Claudia approximately 18.9% of the time, which is closest to the option (b) 19%.
