g red bell pepper seeds germinates 85% of the time. planted 25 seeds. What is the probability that 20 or more germinate

And replacing using the mass function we got:

And adding the values we got:

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:  

The probability mass function for the Binomial distribution is given as:  

Where (nCx) means combinatory and it's given by this formula:  

We want to find the following probability:

And replacing using the mass function we got:

And adding the values we got:
