Does the following describe a binomial experiment? If yes, identify n, p, q, and x.

Cyanosis is the condition of having blueish skin due to insufficient oxygen in the blood. About 80% of babies born with cyanosis recover fully. A hospital is caring for five babies born with cyanosis. The random variable represents the babies that recover fully.

• Yes. n=5, p=.8, q=.2, x= 0,1, 2, 3, 4, 5

• Yes. n=5, p=.8, q=.2, x= 1, 2, 3, 4, 5
