CHS AMDM Basic Probability Assessment

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

P(A) represents the probability of event A occurring.

The probability of an event A is calculated as P(A) = (Number of favorable outcomes) / (Total number of outcomes).

P(rolling a 6) = $$\frac{1}{6}$$ .

Expected number of 6s = 60 * P(rolling a 6) = 60 * $$\frac{1}{6}$$ = 10.

P(electric) = (Number of electric vehicles) / (Total number of vehicles).

In probability, 'or' means to consider the likelihood of either event occurring, often calculated using the addition rule.

The addition rule states that P(A or B) = P(A) + P(B) - P(A and B).

For independent events A and B, P(A and B) = P(A) * P(B).

P(gas or hybrid) = P(gas) + P(hybrid).
