1.- What is the probability of extracting a sphere with a multiple of 7 from the urn? 2.- And to extract a number that is a pair less than 10? 3.- Explain why these two events are or are not mutually exclusive.
In an urn there are 30 spheres numbered from 1 to 30. According to the following events, determine the
Event B: Extract a sphere with an even number less than 10.
Event C: Extract a sphere with a multiple of 3 greater than 15.
Event D: Extract a sphere with an even number equal to or greater than 9.
1.- What is the probability of extracting a sphere with a multiple of 7 from the urn?
2.- And to extract a number that is a pair less than 10?
3.- Explain why these two events are or are not mutually exclusive.
4.- What is the probability of extracting a sphere with a multiple number of 7 or one that is less than 10?
5.- What is the probability of extracting a sphere with an even number equal to or greater than 9 or a multiple of e less than 15?
6.- Events C and D, why are they mutually exclusive or not?
