5. The probability of a "Yes" outcome for a particular binary (yes/no) event is 0.1. For a sample of n=1000 such events, let X be the number of "Yes" outcomes. Use the Normal approximation to the Binomal distribution to answer the following questions.

a. What is the probability the X is less than 80: P(X<80)?

b. What is the probability that X is greater than 115: P(x>115)?

c. What is the probability that the proportion of Yes outcomes is greater than 0.08: P[(X/n)>0.08]?

d. What is the probability that the proportion of Yes outcomes is less than 0.115: P[(X/n)<0.115]?

Discuss how the statistical definitions of “probability,” “experiment,” “outcome,” and “event” differ from the way most people use these terms in everyday life. How would most non-statisticians describe the probability of an event happening if the statistical likelihood of it occurring was .75?

In probability theory, a conditional probability measures the probability of an event given another event has occurred. The conditional probability of A given B, denoted by P(A|B), is defined by P(A|B) = P(A ∩ B) P(B) , provided P(B) > 0. Show that the conditional probability defined above is a probability set function. That is show that a) P(A|B) ≥ 0 [4 Marks] b) P(S|B) = 1. [4 Marks] c) P( S Ai |B) = PP(Ai |B) [4 Marks]

A particular event has a probability of occurrence of p=0.65. Given 12 independent trials, draw the probability distribution and calculate the expected value. A particular event has a probability of occurrence of p=0.65. If each outcome is independent of the last, draw the probability distribution associated with the event not occurring a given number of consecutive times and calculate the expected value. Given the following scenario, determine which distribution (binomial, geometric, hypergeometric) is the most appropriate to model it? Rank...

Explain the outcome of 3^4^5. In particular, what is the order of execution of the two exponentiation operations? Write (5^4^3)−1 as a product of prime numbers. The greatest common divisor of two integers a and b can be written as a linear combination (with integer coefficients k and ℓ) of a and b: gcd(a,b)=ka+ℓb. In Sage this is achieved with the command xgcd. Look in the help page of this command to write the greatest common divisor of 12214...
