Front

How do you calculate the probability of an event?

Back

Probability = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is the probability of drawing a bluegill from a pond with 32 bluegill, 49 catfish, 27 bass, and 12 carp?

Back

Probability = 32 / (32 + 49 + 27 + 12) = 32 / 120 = 8/30.

If two events are independent, what does that mean?

Back

Two events are independent if the occurrence of one event does not affect the occurrence of the other.

What is the probability of getting a number less than 5 on a die roll?

Back

Probability = 4/6 = 2/3.
