Step-by-step explanation:
In the research, it should be noted that this is a Proportion, because worry or not worry is categorical
<h3>What is a proportion?</h3>
A population proportion is the percentage of the population that possesses a particular trait.
For illustration, suppose there are 1,000 people in the population and 237 of them have blue eyes. There are 237 blue eyed people out of every 1,000 people, or 237/1000.
Therefore, it should be noted that this is a Proportion, because worry or not worry is categorical.

The probability of having exactly six seeds germinate is 0.044
Complete Question:
A certain seed has 75% germination rate. Of seven seeds are planted, find the probability of having exactly six seeds germinate.
Step-by-step explanation:
The probability that a seed will germinate is
P(G) = 0.75
The probability that a seed will not germinate is
P(G') = 1-0.75 = 0.25
Therefore the probability that only 6 will germinate can be written as;
P(6/7G) = the probability that 6 seed germinate × the probability that one seed will not geminate
P(6/7G ) =[ P(G)]^6 ×[ P(G')]
P(6/7G) = 0.75^6 × 0.25
P(6/7G) = 729⁄16384 = 0.044
