To solve the problem of finding the probability that at most 6 out of a random sample of 10 people are right-handed, we can use the binomial probability formula. Here’s the step-by-step solution: ### Step 1: Define the parameters We know that: - The probability of success (being right-handed) \( p = 0.9 \) - The probability of failure (not being right-handed) \( q = 1 - p = 0.1 \) - The number of trials (people sampled) \( n = 10 \) ...
