Every spring, Marvin plants colorful flowers in his garden. This year, he decides to plant petunias. He buys them at the garden
store, brings them back home, and starts planting.
The graph shows the proportional relationship between the amount of time (in minutes) Marvin has been working in his garden, x, and the number of petunias he has planted, y.
What does the point (6,3) represent?

Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
<h3>What is the binomial distribution formula?</h3>The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:
n = 4, p = 1/5 = 0.2.
The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:
0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
