if you flip three fair coins, what is the probability that youll get all three tails?
if you flip three fair coins, what is the probability that youll get all three tails?
Answer
Explanation:
Step1: Determine single - coin probability
The probability of getting tails on a single fair coin flip is $\frac{1}{2}$.
Step2: Use multiplication rule for independent events
Since coin flips are independent, the probability of getting tails on three flips is $\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}$. $\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}=\frac{1}{8}$
Answer:
$\frac{1}{8}$
