If an event, E can occur m ways out of n possible outcomes, the probability of that event is given by P(E) = (m/n). Example:
1. Problem: What is the probability of
rolling a 3 on a die
Solution: On a fair die (not the kind
you play with in Vegas, where
everything is rigged),
there are six equally likely
outcomes when you roll. Also,
there is only one way to get a
By the definition of proba-
bility, P(3) = (1/6).
Probability will always be a fraction, 0, or 1. If an event cannot happen, the probability is 0. If an event is certain to happen, the probability is 1.
i hope this helps...
im thinking 6/20, which is 3/10 is a wood racket thats defective
