Probability

Anotações:

• For an event where all outcomes are equally likely: P(E)= All favourable outcomes             ---------------------------------              All possible outcomes

1. All possible outcomes

Anotações:

• Expected frequency= Theoretical possibility x number of trials

1. The expected number of times an event will occur

Anotações:

• P(E) = P(not E) = 1

1. Make up the sample space
2. An event complement to another is the opposite event

1. The range of probability is from 0-1
   1. Anything closer to 1 is likely
   2. Anything closer to 0 is unlikely
   3. 0.5 is an even chance
