A dice is thrown what is the chance of getting 5,6 or a number divisible by 4?

Question No: 1 A pair of dice is rolled. Let A be the event of getting sum of 3 and B be the event of getting sum of 5. Explain whether these events are mutually exclusive or collectively exhaustive. What is the probability of getting A or B? (Marks 5) Question No: 2 A fair coin is tossed four times. What is the probability of getting a. Exactly 2 heads.

What is the probability that tourists will see at most four lions on the next one-day safari? Use POISSON function. (Marks 5) Question No: 4 Find area under one tail for z-value of 1.75 i-e area under curve for the region shaded with blue. a) Using Standard Normal Distribution Table b) Using NORMSDIST excel function. (Marks 5) HINT: Standard normal curve is a normal curve with mean zero and standard deviation 1. Area between two values of Z (say, a and b) represents the probability that Z lies between a and b.

As with any continuous probability function, the area under entire standard normal curve must be equal to 1. So area under the right half and the left half, of the curve is 0.5

----------------------------------------------------------------------------------------------------------The Standard Normal Distribution Table gives the area under curve from 0 to Z

-----------------------------------------------------------------------------------------------------------

NORMSDIST excel function returns area under standard normal curve from negative infinity to Z

Question No: 5 Suppose scores on an IQ test are normally distributed. If the test has a mean of 100 and a standard deviation of 10, what is the probability that a person who takes the test will score exactly 90? (Marks 5) Question No: 6 Suppose we want to estimate the average weight of an adult male in a town. We draw a random sample of 1000 men and weigh them. We find that the average man in our sample, weighs 180 pounds, and the standard deviation of the sample is 30 pounds. What is the Standard Error of the Mean? Calculate 95% confidence interval. (Marks 5) HINT: Take standard deviation of sample as an approximation of standard deviation of the population.
