**Probability** is a measure of the likelihood that a given event will occur. The value of probability ranges from 0 (impossible event) to 1 (certain event).
The probability of an event is calculated using the formula:
Probability (P) = Number of favorable outcomes / Total number of possible outcomes
Example 1: What is the probability of rolling a 3 on a fair six-sided die?
Step 1: Total number of possible outcomes = 6 (since the die has six sides). Step 2: Number of favorable outcomes = 1 (only one side has a 3). Step 3: Probability = 1/6 ≈ 0.167.
Example 2: What is the probability of drawing a heart from a standard deck of 52 cards?
Step 1: Total number of possible outcomes = 52 (total number of cards). Step 2: Number of favorable outcomes = 13 (since there are 13 hearts in a deck). Step 3: Probability = 13/52 = 1/4 = 0.25.
Calculate the probability of drawing a king from a standard deck of 52 playing cards.
Hint: There are 4 kings in the deck. Total number of cards = 52.
The formula is the same as in the examples above. Try calculating the probability!
