Probability Question about Beetles?

Approximately 37% of the world's insects are beetles. If a student collected a sample from her university campus and determined whether or not each sampled insect was a beetle. Assuming the global proportion of beetles is maintained at the scale of the university campus, calculate the probability that 150 or less of the insects are beetles.

    150 / 406 is around 37%

      I am trying to calculate the probability that in the sample of 444 insects collected, that 150 or less of the insects are beetles.

    Don't you need to know how large the sample is? The answer would be different if it was 150 versus 1000.
