(a) If A and B are independent events with P(A) = 0.6 and P(B) = 0.7, find P (A or B).

(b) A randomly selected student takes Biology or Math with probability 0.8, takes Biology and Math with probability 0.3, and takes Biology with probability 0.5. Find the probability of taking Math.

A box contains 4 blue, 6 red and 8 green chips.

In how many different ways can you select 2 blue, 3 red and 5 green chips? (Give the exact numerical value).

Draw two chips in a row without replacement. Find the probability that both chips are green.

Based on the following table, compute the probabilities below:

	YES	NO	NO OPINION	totals
MEN	50	30	20	100
WOMEN	120	40	40	200
totals	170	70	60	300

P (Women and Yes) =

P (Men | Yes) =

P (No | Women) =

P (Men or No) =

Are Men and No Opinion mutually exclusive?

Are Men and No Opinion independent? Justify your answer by an appropriate computation.
