Identify Total Possible Outcomes: Identify the total number of possible outcomes when rolling a six-sided die. $\newline$ A standard six-sided die has $6$ faces, each with a different number from $1$ to $6$ . Therefore, there are $6$ possible outcomes when the die is rolled.
Identify Favorable Outcomes: Identify the number of favorable outcomes for rolling a $1$ . Since there is only one face with the number $1$ , there is only $1$ favorable outcome for this event.
Calculate Probability of Rolling a $1$ : Calculate the probability of rolling a $1$ . The probability $P$ of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. $P(\text{rolling a 1}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$ $P(\text{rolling a 1}) = \frac{1}{6}$
Determine Probability Description: Determine the word or phrase that describes the probability of rolling a $1$ . Since the probability of rolling a $1$ is $1$ out of $6$ , it is not ＂an equal chance or $50$ - $50$ ＂ (which would imply a probability of $1/2$ ), it is not ＂certain＂ (which would imply a probability of $1$ ), and it is not ＂likely＂ (which would imply a probability greater than $1/2$ ). The probability of $1/6$ suggests that it is ＂unlikely＂ but still possible.
