Practicing Success
If a coin is tossed three times, then the probability of getting at least one tail is |
\(\frac{1}{3}\) \(\frac{1}{8}\) \(\frac{3}{8}\) \(\frac{7}{8}\) |
\(\frac{7}{8}\) |
\(\begin{aligned}P(\text{ Getting at least one tail in three tosses })&=1-P(\text{ getting head in all three times })\\ &=1-\frac{1}{8}\\ &=\frac{7}{8}\end{aligned}\) |
