A sample of eight orthopedic patients on your unit includes two patients on intravenous anticoagulants, four patients on oral anticoagulants, and two patients on subcutaneous anticoagulants.

Hip replacement patients have the same probability of being on oral anticoagulants as the orthopedic patients in your previous study, and you have four in your daily assignment. Calculate the number of patients with hip replacements who you anticipate would need oral anticoagulants.
