Range is the range of the y-axis.
Although we see that the "line" ends at a specific point, it is neither the highest or lowest y-value.

Answer:
The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
Step-by-step explanation:
The proportion of pink bulbs is p=0.4.
If X is the amount of pink bulbs in a group of 4 bulbs, we can model this as a binomial distribution problem.
The probability that at least one of the bulbs is pink is P(X≥1)
The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
