Using for loop to compute parameters

I want to use FOR LOOP to find i in this equation "pbinom(0.975,30,i) =4" i range from 0 to 1.
Thank you very much !!!

Do it then.

Are you coming across a problem? Post the code and an error. Also check out the purrr package.

i is a probability; so it must be between 0 and 1.

A loop isn't needed

vector_of_probabilities <- seq(0.1:0.4, by = 0.1)
pbinom(q = 0.975, size = 10, p = vector_of_probabilities)
#>  [1] 0.3486784401 0.1073741824 0.0282475249 0.0060466176 0.0009765625
#>  [6] 0.0001048576 0.0000059049 0.0000001024 0.0000000001 0.0000000000
