Mr. X invites 15 relatives to a party: his mother, three uncles, two aunts, four brothers, and five cousins. If the chances of any one guest arriving first are equally likely, find the following probabilities:
a. the first guest is an uncle or a cousin
b. the first guest is a brother or a cousin
c. the first guest is an uncle or her mother
Total No# of Relatives = 15
a) No of Uncles = 3
No of Cousins = 5
Probability = Number of success ...
The probability from a given situation is calculated. The probability of different party guests arriving are determined.
