Question

A new antibiotic is effective for 85% of infections. The antibiotic is given to 40 patients.

a) What is the probability that the antibiotic will work in less than half of the patients?

Answer 1

Half the patients is 20. So less than 20 is 19. Hence, here it describes \[P(X<20)=P(X≤19)\]
