Implementing two‑factor authentication (2FA) reduces this probability by 80\%. The organization rolls out 2FA to 60\% of the accounts, while the remaining 40\% continue with password‑only protection. Calculate the overall percentage reduction in the expected number of unauthorized accesses per year after the partial 2FA implementation.
