Q. What is the probability of flipping tails and rolling a one?

\newline

\newline

Write your answer as a fraction or a whole number. With fractions, use a slash (

/

) to separate the numerator and denominator.

\newline

\_\_

Identify Probability of Tails: Identify the probability of flipping tails on a coin. A coin has two sides, heads and tails, so the probability of flipping tails is $1$ out of $2$ . Calculation: Probability of tails = $\frac{1}{2}$
Identify Probability of Rolling One: Identify the probability of rolling a one on a six-sided die. A standard die has six faces numbered from $1$ to $6$ , so the probability of rolling a one is $1$ out of $6$ . Calculation: Probability of rolling a one = $\frac{1}{6}$
Calculate Combined Probability: Calculate the combined probability of both independent events happening (flipping tails and rolling a one). $\newline$ To find the probability of both events happening, multiply the probabilities of each event. $\newline$ Calculation: Combined probability = $(\frac{1}{2}) \times (\frac{1}{6}) = \frac{1}{12}$
