Probability involving “at least one success”

• Get the probability of “all successes” then subtract that from 1
• E.g. Lebron is a 75% free throw shooter. What’s the likelihood that he misses at least 1 out of 3 free throws?
  • Probability of all successes = .75^3 = .422
  • Probability of at least one miss = 1 - (.75^3) = .578
