[4/9, 9:36 AM] Kiprutohsangkoros: Which of the following statements are true?

Probability is a measure on the likelihood that something will occur.

Two events A and B are independent if P(A)=P(A|B).

A probability is a number between -1 and 1, where 1 indicates certainty and -1 means impossible.

A statistical probability must be very close to its corresponding theoretical probability. Two events A and B are mutually exclusive if P(A)+P(B)=1.
