Suppose that two integers from the set of 8 integers {1, 2, … , 8} are choosen at random. Find the probability that

5 and 8 are picked.

Both numbers match.
Sum of the two numbers picked is less than 4.

[3+3+4 marks] Suppose that you pick a bit string from the set of all bit strings of length ten. Find the probability that:

The bit string has the sum of its digits equal to seven.
The bit string has more 0s than 1s.

The bit string has exactly two 1s, given that the string begins with a 1

Suppose we are given a set ? containing 2? integers, and we wish to partition it into two sets ?1 and ?2 so that |?1 | = |?2 | = ? and so that the sum of the numbers in ?1 is as close as possible to the sum of those in ?2. Let the neighborhood ? be determined by all possible interchanges of two integers between ?1 and ?2. Is ? exact?

In Java, a set of integers is given. write a function to find 2 integers in this set that sums upto a target value. i.e [1,5,2,0,11,3] target = 7 result [5,2] i.e [1,5,4,0,14,-7] target = 9 result [5,4] NOTE: THE SAME INTEGER CANNOT BE USED TWICE !!!

Suppose that you are given a set of words; and two words from the set: word 1 and word 2. Write a program which will transform word 1 into word 2 by changing a single letter in word 1 at a time. Every transition that word 1 takes will have to be in the set of words. You must output the smallest sequence of transitions possible to convert word 1 into word 2. You may assume that all the words...

Suppose you receive utility ?(?, ?) = 8? 1/2 + ? from ? Instagram “likes” and l minutes worked. Assume it takes 2 minutes to find an Instagram post to like, and you have 60 minutes to spend on work or Instagram. Assume your goal is to maximize your utility. a) How many Instagram posts will you like? How many minutes will you work? b) What is your total utility if you make the optimal choices above? c) Suppose the...

The Fibonacci sequence is the series of integers 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 . . . See the pattern? Each element in the series is the sum of the preceding two elements. Here is a recursive formula for calculating the nth number of the sequence: Fib(N) = {N, if N = 0 or 1 Fib(N - 2) + Fib(N - 1), if N > 1 a) Write a recursive method fibonacci that returns...
