Solution 1

To solve this problem, we can use the binomial probability formula. The binomial probability formula is given by:

[ P(X = k) = \binom{n}{k} p^k (1-p)^{n-k} ]

where:

  • ( n ) is the number of trials (in this case, 10 people),
  • ( k ) is the number of successes (in this case, 3 left-handed peop Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
