Suppose A and B are mutually exclusive events defined on the same sample space such that 𝑃(𝐴)=0.37 and 𝑃(𝐵)=𝑐.

Question 11

What is the maximum value of 𝑐?

Question 12

What is 𝑃(𝐴|𝐵)?

In a batch of 15 jars of instant coffee, 5 have been under filled. Suppose 6 of these jars are selected without replacement. If more than 1 of these selected jars are under filled, the whole batch is sent back for refill. What is the probability of the batch being sent back for refill? (Round off to 2 decimal places.)

Two-tailed test, o? is known, a= 0.05, n= 45

What is the value resulting from subtracting the maximum error from the sample mean?

In a batch of 15 jars of instant coffee, 5 have been under filled. Suppose 6 of these jars are selected without replacement. If more than 1 of these selected jars are under filled, the whole batch is sent back for refill. What is the probability of the batch being sent back for refill?

There is a bag filled with 3 blue, 2 red and 4 green marbles. A marble is taken at random from the bag, the colour is noted and then it is not replaced. Another marble is taken at random. What is the probability of getting 2 different colours?

The probability that a person, living in a certain city, owns a dog is estimated to be 0.3. Find the probability that the

tenth person randomly interviewed in that city is the fifth one to own a dog

Use the standard normal probability table to find the value z for each of the following.

(a) P (0≤Z≤z) = 0.41 (b) P(Z≥z) = 0.25

(c) P (Z≤z)= 0.95 (d) P(-z≤Z≤z) = 0.88
