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.
no
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
Define binomial experiments and provide an example.
An example of a binomial experiment is rolling a fair six-sided die
A binomial experiment is a statistical experiment that has an infinite number of trials
A binomial experiment is a statistical experiment that has the following properties: it consists of a fixed number of trials, each trial has only two possible outcomes (success or failure), the probability of success remains constant for each trial, and the trials are independent of each other.
The probability of success in a binomial experiment changes with each trial
Explain the characteristics of binomial experiments.
Having a fixed number of trials, each trial having only two possible outcomes (success or failure), and the probability of success remaining constant for each trial.
Having an unlimited number of trials
Each trial having multiple possible outcomes
The probability of success changing for each trial
What are the two possible outcomes in a binomial experiment?
Positive and negative
Win and lose

In a binomial experiment, what does it mean for the trials to be independent?
The outcome of one trial is predetermined by the outcome of another trial
The outcome of one trial affects the outcome of another trial
The outcome of one trial does not affect the outcome of another trial
The trials are conducted at the same time
If you flip a coin 50 times, what is the probability of getting exactly 25 heads?

At a certain intersection, the light for westbound traffic is red for 16 seconds, yellow for 4 seconds, and green for 30 seconds. Find the probability that out of the next eight westbound cards that arrive randomly at the light, exactly three will be stopped by a red light.
