. (a) How many different positive three-digit whole numbers can be formed from
the four digits 2, 6, 7, and 9 if any digit can be repeated?
(b) How many different positive whole numbers less than 1000 can be formed
from 2, 6, 7, 9 if any digit can be repeated?
(c) How many numbers in part (b) are less than 680 (i.e. up to 679)?
(d) What is the probability that a positive whole number less than 1000, chosen
at random from 2, 6, 7, 9 and allowing any digit to be repeated, will be less
than 680?
7. Answer question 7 again for the case where the digits 2, 6, 7, 9 can not be repeated
Academicians was surveyed of their loyalty to the university. They're asked “If given an offer by other university equivalent or slightly better than present position, would you remain or not?Table 4 represents the responses of the 200 academicians which were cross-classified with their length of service.
Table 4: Loyalty of Academicians & Length of Service.
Length of Service Total
Loyalty Less than1 yr, 1-5 yr, 6-10 yr, More than 10 yr
Remain 10 30 5 75 120
Not remain 25 15 10 30 80
a)represent the information in Table 4 as a tree diagram.
b)What's the probability of randomly who is loyal and who has more than 10 yr service?
c)What's the probability of who would not remain and has less than 1-yr of service?
d)What's the probability of who would remain, given that he or she has 1-5 yr of service?
e)What's the probability of who would not remain, given that he or she 6-10 yr of service?

Assign an oxidation number to each element in the reaction.
CO(g) + 2H2(g) → CH3OH(g)
In CO, the oxidation number of C is , and that of O is . In H2, the oxidation number of H is . In CH3OH, the oxidation number of C is , that of O is , and that of H is .
Solve y’=y-x2
, y(0)=1, by Picord’s method upto the third approximation . Hence find
the value of y(0,1), y(0,2)
