The probability all penguins migrate is 0.05.
Let p be one penguin's success probability, n the number. Then p^n = 0.05. We need (1-p)^n. For n=1, (1-0.05)=0.95, but "all" suggests multiple.
For n=2, p^2=0.05, p≈0.2236, (1-p)^2≈0.6025, varying with n. Without n, it’s indeterminate. Answer: E.

p(completing migration) = 0.05
p(completing migration) + p(not completing migration) = 1
But above can be only possible, if there are only two possibilities. There might be possibility of some completing migration and some not also.
So, the answer is E. It cannot be determined by the given imformation.
