Answer:

Step-by-step explanation:
The probability we want to calculate is:

Now, we use the normal approximation of the binomial distribution
That would be:
p = 0.8 (probability of germination) given as 80%
q = 1 - p = 0.2 (probability of no germination)
We have the mean as:

We have the standard deviation as:

Now, let us get the value of z;

Now, we use the standard normal distribution table
