Answer:
C.) Number of successful trials / Total number of trials
Step-by-step explanation:
The empirical probability of an event 'E' is defined as :
(Number of successful occurrences of event 'E' / Total number of trials)
The empirical probability requires that an experiment of a chosen number of trials be performed. The ratio of the number of success to the total number of trials is used to estimate the empirical probability of such event.
P(Empirical) = (Number of successful trials / Total number of trials)
This is different from the use of sample space in the evaluation of theoretical probability whereby all possible occurences is used to estimate the probable outcome of an event.
P(theoretical) = (number of required outcomes / total number of possible outcomes)
Answer: There are 126 red key chains.
Step-by-step explanation:
1. You know that 10% are yellow, then:
350*0.1=35 (35 key chains are yellow).
2. And you know that of the remaining key chains 3/5 there are green.
The remaining is:
350-35=315
Then:
325*3/5=189 (189 key chains are green).
3. Then, the number of key chains that are red is:
350-35-189=126 (126 key chains are red).
