The events A and B are mutually exclusive. Suppose P(A)=0.30 and P(B)=0.40. What is the probability of either A or B occurring? what is the compliment of event A? What is the meaning?

1. You possess a 'standard deck of playing cards' (n = 52). First,
(a) identify the probability of selecting a spade, club, or heart. Second,
(b) calculate the probability of selecting a spade, heart, diamond, or face card. Identify
(c) the probability of selecting (in sequence) a two and a red jack (assuming that the fi

A contingent liability should be created if it probable that the liability will occur and the amount of the loss can be reasonably estimated.
How is the probability of an eventoccurring determined? Is this based on an estimate of the likelihood of the eventoccurring?

The probability distribution for the random variable x is as follows
x is 20 25 30 35
f(x) is .20 .15 .25 .40
a. Is this probability distribution valid? Explain.
b. What is the probability that x=30?
c. What is the probability that x is less than or equal to 25?
d. What is the probability that x is greater than 30?

12. Let E, F, and G be three events. Find expressions for the events so that of E, F, and G:
(a) only E occurs;
(b) both E and G but not F occur;
(c) at least one of the events occurs;
(d) at least two of the events occur;
(e) all three occur;
(f) none of the events occurs.

A silver dollar is flipped twice. Calculate the probability of each of the following occurring:
a. a head on the first flip
b. a tail on the second flip given that the first toss was a head
c. two tails
d. a tail on the first and a head on the second
e. a tail on the first and a head on the second or a head on the first a

In a region, 20% of the population has brown eyes. If 15 people are randomly selected, find the probability that at least 13 of them have brown eyes. Is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes?
- The probability at least 13 of 15 have brown eyes = ____ (three decimal places

Let E and F be non-zero-probabilityevents. If E and F are mutually-exclusive, can they also be independent? Explain the answer, and also prove it algebraically using the definitions of mutually-exclusive and independent events.

Based on the attached Excel sheet determine:
1. The probability of cases being appealed and reversed in the three different courts.
2. Rank the judges with each court. State the criteria you used and provide a rationale for your choice.
