Answer:
Step-by-step explanation:
Let the A be the amount Alice initially has and B be Bob's initial amount.
#Alice receives $n from Bob:
#Alice gives n to Bob:
#We simultaneously solve the two expressions:
The initial amounts of Alice is -8n and Bob's is -27n
#We find the ratio of Alice:Bob:-
Hence the ration of Alice to Bob is 8:27
Answer:
(a) 0.10
(b) 0.70
(c) 0.30
Step-by-step explanation:
Items b and c are missing from the question:
(b) What is the probability that at least one of the two members whose name begins with C is selected?
(c) If the five faculty members have taught for 3, 6, 7, 10, and 14 years, respectively, at the university, what is the probability that the two chosen representatives have a total of at least 18 years teaching experience there?
The number of ways to select two representatives out of 5 people is given by the combination of picking two out of 5:
(a) Since there is only one way for both Anderson and Box to be selected, the probability is:
(b) There are four ways for Cox to be selected, four ways for Cramer to be selected, and one where both are selected. The probability is:
(c) The only possible ways for the total of number of years to exceed 18 is by selecting: (14;6 14;7 14;10). Therefore the probability is:
