Homework Statement
Each year, 5.7% of archers develop repetitive strain injury (RSI) in their arm.
Each year, 3.6% of archers develop problems related to eye strain.
However, 91.2% of archers develop neither.
(a) Formally define sensible event notation, and summarise the information in the question.
(b) List the elements in the sample space using formal notation.
(c) What is the probability that an archer develops both RSI and eye strain in a particular year?
(d) With regard to archers, are the two problems of developing RSI and developing eye strain statistically independent? Briefly explain why or why not.
Homework Equations
Have to choose between bernoulli, binomial, poisson, geometric, hyper geometric and negative binomial methods
The Attempt at a Solution
a) let P(a) = 5.7%, P(b)=3.5%, P(c)=91.2%
P(A∪B∪C)=1
b)S{P(a), P(b), P(c)}
c) 1-0.912 = 0.088
d) They are statistically independent since they affect separate parts of the body and the problems caused do not necessarily have an effect on the development of either ailments.
