The document contains two examples involving binomial distributions:
1) The probability of a component surviving a shock test is 3/4. The question asks for the probability that exactly 2 of the next 4 components will survive.
2) The probability that a patient recovers from a rare blood disease is 0.4. The question asks for the probabilities of: a) at least 10 of 15 people surviving, b) between 3 to 8 of 15 people surviving, and c) exactly 5 of 15 people surviving.
The document discusses the binomial distribution, which models the number of successes in a fixed number of independent yes/no experiments, called Bernoulli trials, where the probability of success p is the same for each trial. It provides examples of binomial experiments and calculations. Key points covered include the definition of a binomial random variable X with parameters n (number of trials) and p (probability of success), and that the mean and variance of X are np and np(1-p) respectively. Examples calculate probabilities of outcomes and compare values to means and standard deviations.
The document appears to be a class roster listing students' names, scores on various assignments and exams, and total scores. It includes information on 48 students, listing their names, scores on assignments like tests, quizzes and projects, and overall percentages.

Solution to first semester soil 2015 16chener Qadr
This document contains a soil mechanics exam with four questions. Question 1 involves determining properties like void ratio, dry density, and bulk density of a saturated soil sample. It also asks about changes if saturation is reduced and calculating soil requirements for an embankment. Question 2 asks to classify a soil sample using soil classification charts and determine its suitability as backfill. Question 3 involves calculating seepage flow from a canal into a ditch based on soil properties. Question 4, which is not fully summarized, involves analyzing seepage in an embankment dam.
This document contains a soil mechanics exam with four questions. Question 1 involves calculating the factor of safety for a cut in stiff clay. Question 2 calculates total stress at a point below two foundations. Question 3 involves drawing shear strength envelopes from triaxial test data. Question 4 determines shear strength parameters from direct shear tests and uses them to calculate initial cell pressure in a triaxial test.
