Suppose that historically, 35% of applicants that are offered admittance to Texas Tech actually enroll, while the others take offers somewhere else. If Texas Tech will accept 9300 this coming year, what is the probability that less than 3250 will actually enroll? Use the normal approximation to the binomial. P(X < 3250)
Prob-1 Probability that cars have been assembled in a particular plant as follows: P(plant1)=20%, P(plant2)=24%, P(plant3)=25%, P(plant4)=31% Warranty claim rate of cars manufactured by plant3: 6%. If 352,500 of cars do not claim warranty in plant3; compute total number of cars manufactuted by all plants in a year? Sol:
A random variable follows a binomial distribution with a probability of success equal to 0.62. For a sample size of n=7 Find the probability of exactly 3 successses P(x=3)=
It's desired to model the random variable X with a shape that rises to a peak near x=6 and whose possible values are integers 1-6. Copy paste the following lines of code into R: x <- 1:10 shape <- x*(12-x) barplot(shape, names. arg=x) This "shape" isn't a valid PMF because the numbers don't sum to 1. Convert the numbers in "shape" to valid probabilities and report P(X-5). Copy/paste all digits from R into your answer here.
Suppose that 5 friends go to a carnival and each tries once to pop a balloon with a dart to win a prize. Jen plays darts regularly and will pop a balloon on 80% of her attempts, Bob has never thrown a dart and will pop a balloon only 25% of the time, and the 3 other friends will all pop a balloon about half the time. Let X be the number of balloons popped by the 5 friends. Does X have a binomial distribution?
What should be the value of a to make this continuous random variable X valid?
X is the number of defective parts in a sample of 10 randomly selected parts coming from a manufactoring process in which 1.5% of all parts are defective. How do I find the probabilty the sample contains no broken parts?

Many people believe that the daily change in price of a company's stock in the stock market is a random variable with mean 0 and variance o² during the middle 2 months between 2 earning report dates when there is not much news released. That is, if Yn represents the closing price of the stock on the nth trading day of that period, then Yn = Yn-1+Xn, for 1 ≤ n ≤ 60, where X₁, X2,..., X60 are independent and identically distributed random variables with mean 0 and variance o². Suppose that the stock price at the beginning of the 2-month period is 100. If o = 2, what is the approximate probability that the stock's closing price on the 30th trading day will exceed 110, i.e., what is P(Y30 > 110)
