To find the probability of having high waves on three consecutive days, we can multiply the probability of high waves on a single day by itself for three days: \[ P(\text{3 consecutive days}) = P(\text{high waves})^3 = 0.22^3 = 0.010648. \] So, rounding it gives us approximately 0.0106. The correct answer is **A. 0.0106**. For future reference, when dealing with probabilities over multiple independent events, be sure to multiply the probabilities together. It’s a crucial skill for all types of probability puzzles or real-life applications like weather forecasting! Always check if events are indeed independent before applying this rule.
