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)Probablity an event is likely to occur?
b) P of an impossible event?
c) Sample space consists of 25 separate events equally likely. What is P of each?
d) True/False test. P of correct if a random guess?
e)Multiple choice test with 5 possible answers for each, P of getting correcdt of random guess?
It can be easy enough to get the addition rule and the multiplication rule confused. Tell me the difference between the two. Provide the notations and then tell me what type of problem I would use each one for.
Notation for Addition Rule: P(A or B) = P(event A occurs or event B occurs or they both occur).
Johnson Chemicals is considering two options for its supplier portfolio. Option 1 uses two local suppliers. Each has a "unique-event" risk of 5%, and the probability of a "super-event" that would disable both at the same time is estimated to be 1.5%. Option 2 uses two suppliers located in different countries. Each has a "unique-
At the first tri-city meeting, there were 8 people from town A, 7 people from town B, and 5 people from town C. If the council consists of 5 people, find the probability of 3 from town A and 2 from town B.
