theoretical probability definitions
# Definition Sets
1probability based on comparing the number of possible favorable outcomes to the number of total possible outcomes9 sets
2the ratio of the number of favorable outcomes to the number of possible outcomes if all outcomes have the same chance of happening.3 sets
3what should occur in a probability experiment3 sets
4when all outcomes are equally likely, the theoretical probability of an event is the ratio of the number of favorable outcomes to the number of possible outcomes.2 sets
5the ratio of the number of ways an event can occur to the number of possible outcomes.2 sets
6the ratio of the number of favorable outcomes to the number of possible outcomes2 sets
7what we think will happen based on mathematical calculations2 sets
8when all outcomes are equally likely2 sets
9probability based on what should happen in an experiment2 sets
10# of favorable outcomes/# of possible outcomes2 sets
11ratio of the favorable outcomes to the possible outcomes of an event2 sets
12the ratio of the number of favorable outcomes to the total possible2 sets
13a statement of the probability of an event without doing an experiment or analyzing data.2 sets
14used when an observation is not based on an actual experiment. in other words, you predict what will haven passed on some observations1 set
15used when each outcome in a sample space is equally likely to occur1 set
16is a likelihood that an event will happen based on fact, not tested1 set
17(13-1)-what should happen, equal theory.1 set
18estimating the how likely an event will occur when all outcome are equally likely1 set
19the ratio of the number of ways an event can occur to the total number of possibilities in that situation1 set
20the ratio of the number of favorable outcomes to the number of possible outcomes; it is something that should happen1 set
21ratio of the number of ways an event can occur to the number of possible outcomes1 set
22describes how likely it is that an event will happen- based on all the outcomes when the outcomes are equally likely1 set
23what should happen in a probability experiment1 set
24number of favorable outcomes/total number of outcomes1 set
25the likelyness of an outcome1 set
26ratio of # of equally likely outcomes in an event to total # of possible outcomes1 set
27when probability is determined without actually doing an experiment1 set
28based on theoretical principles- don't change1 set
29determined by the mathematically analyzing a situation and its possible outcomes1 set
30what should occur in a probabilty experiment1 set
31what "should" happen mathematically1 set
32determining the likelihood of an event without conducting an experiment1 set
33favorable events/possible events1 set
34a probability found by analyzing a situation1 set
35when p(event)=number of favorable outcomes/number of possible outcomes1 set
36the calculated probability1 set
37comes from a model (ex. equally likely outcomes)1 set
38probability that is based on theoretical principles rather than on actual experience1 set
39the likelihood that an event will have a particular outcome, or what "should" happen, based on math1 set
40probabilities based on known characteristics or facts.1 set
