Patricia finds that the experimental probability that a dog want to go outside between 4 PM and 5 PM is 7/12 about what percent of the time does your dog not want to go out between 4 PM and 5 PM

Respuesta :

Let E be the event "a dog want to go outside between 4 PM and 5 PM", 

then    not E     or    the complement of E,   E'   is:

E' : "a dog does not want to go outside between 4 PM and 5 PM"


E and E' complement each other, so the probability of one of these to happen is 1 - the probability of the other.

P(E')= 1-P(E)=1-7/12=5/12

Answer: 
P( a dog does not want to go outside between 4 PM and 5 PM)=5/12
