What is the highest probability

Question

At a faculty the probability of seeing a person greater than 190cm is 12%. From a class of $24$ people, is it more reliable to meet $2$ people above $190cm$ or $4$ people above $190cm$?

I dont undersand. Consider that the solution may be related to any distribution (Binomial or Poisson). Help me please to solve. Thanky very much for my hard?

Here is a binomial distribution for $p=0,12$ and $n=24$:

$\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}$, what is k=? please – Madrit Zhaku Mar 30 '20 at 16:32
$k$ is a number of sucsseses. It runs from 0 to 24. You are interested what is happening if $k=2$ and $k=4$. – nonuser Mar 30 '20 at 16:32
Case 1 :$\frac{24!}{2!(22)!}0.12^2(0.88)^{22}$; Case 2 :$\frac{24!}{4!(20)!}0.12^4(0.88)^{20}$; – Madrit Zhaku Mar 30 '20 at 16:33
Yes, and a "graph" of this function is drawn in the answer. – nonuser Mar 30 '20 at 16:35
can you give me any other explanation about the picture that is unclear, you were very clear about the example – Madrit Zhaku Mar 30 '20 at 16:37
can i ask you for another example, or will i have to post it, you made the example very clear, you are extraordinary – Madrit Zhaku Mar 30 '20 at 16:39
It is a graph of function $f(k) = {24\choose k}0,12^k\cdot 0,88^{24-k}$ where $k$ runs from $0$ to $24$. – nonuser Mar 30 '20 at 16:39
