Mr. Jones has insomnia once a week. If he had an insomnia, he will definitely drink a cup of coffee in the morning. If he got a good night sleep, he will drink coffee with probability 1/2. Let I be the event that he has insomnia. Let C be the event that he drinks coffee in the morning. Given the information above: P(I) = 1/7, P(C|I) = 1 and P(C|I) = 1/2.

Find probability that he drinks coffee in the morning.

Step-by-step explanation:

Given:

I is the event that he has insomnia.

C is the event that he drinks coffee in the morning.

We want to determine the probability that he drinks coffee in the morning, P(C).

Using the Law of Total Probability

The probability that he drinks coffee in the morning is

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
