113.038.05 Probability - Probability involving at least one success

# 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

- Probability of all successes =
