From the data given below: Compiles on First Run 72 Does not Compile on First Run Total C++ 48 120 Java 64 16 80 Total 136 64 200 a) What is the probability that a program will compile on the first run given that it has been written in C++? b) Given that it is written in Java, what is the probability that program selected at random will compile on the first run?
To set up a password for a computer account, the password must consist of two lowercase letters (a to z) followed by one capital letter (A to Z) followed by four digits (0,1,...,9). For the following two questions, you can leave the answers in multiplicative and fraction forms. (a) Find the total number of possible passwords. (b) Find the probability that the password contains at least one repetition in the letters or numbers. Note that the same letter in lowercase and in capital letter is considered as a repetition, for example, abA1234 is considered having a repetition in letter “a”.
(Strings of letters) On a certain planet, there are 410 inhabitants, each of which has a unique 10-letter identifier. Each letter is either A, B, C or D, so there are 4¹0 different identifiers, and every identifier is currently in use. Identifiers look like CBAADAABBB or AADABCAACC. An inhabitant of the planet is now chosen uniformly at random (that is, each inhabitant has the same probability of being chosen). What is the probability that the identifier of the chosen inhabitant (c) is a palindrome? (d) has no two consecutive identical letters?

Consider a binary code with 4 bits (0 or 1) in each code word. In each code word, abit is a zero with probability 0.6, independent of any other bit.(a) What is the probability of the code word 0101?(b) What is the probability that a code word contains exactly two ones?
sketch a 5-input, 3-output switching element. time is slotted and synchronized for inputs. One slot holds at most one packet. A packet arrival processes to each input are Bernoulli (with arrival probability p for a packet in each slot and non arrival probability 1-p in each slot) (a) write an expression for the probability of one or more arrivals in a slot. (b) find the throughput at the output (c) write an expression for the probability in a slot that the top 3 inputs have packets and the bottom 2 doesn't have a packet. (d) for what values of p is the probability of 2 arrivals at the input greater than the probability of ine arrival at the inputs?
Consider a binary code with 6 bits (0 or 1) in each code word. An example of a code word is 010010. How many different code words are there? b. How many code words have exactly three O's? In each code word a bit is a 0 with probability 0.8, independent of any other bit, what is the а. С. probability of observing the code 001111. d. What is the probability that the code word will contain exactly three zeros (Hint: The way that you would read this statement is the P[observing exactly three zeros] = P[000111] + P[100011] + as you can see there are so many ways you could observe 3 zeros in a code, use the %3D etc combinatorics principle to help you find the probability in this question )
