week 5 - probability
Cards in this deck (22)
- 1Define random experimentsobservational process where results can't be shown in advance
- 2what is set of possible outcomes also known assample space (s)
- 3what are the different types of sample spaces?- infinite or finite
- discrete or continous
- countable or uncountable - 4A discrete sample is either- finite or countably infinite
- 5A continuous sample is ?uncountably infinite
- 6what is an event?any subset of outcomes in a sample space
- 7A simple event /elementary sample is also known asa single outcome
- 8what does a discrete sample consist ofall the simple events
s = (E1, E2... En) - 9what does all the events have in commonan equal chance of occuring
- 10what does a compound even consist of- two or more simple events
- 11Define probabilitya number that measures the relative likelihood that an event will occur
- 12What does the p(a) need to lie between0 - 1
- 13write the equation for the p(a)0 < (line under)p (a) < (line under)1
- 14what does the 0 meanif p = 0 an event cannot occur
- 15what does the 1 meanan event is certain to occur
- 16what sum sum in discrete samples should all events add up to1
- 17Approaches of probability ...-
- 18define the empirical approachestimated from observed outcome frequency
- 19give an examplethere is a 3.2 chance of twins in a randomly chosen birth
- 20what is the classical approach?known as the the prior by the nature of the experiment
- 21give an example of a classical probabilitythere is a 50% chance of heads on a coin flip
