qw: A photon is incident on a beam-splitter. At high light intensities, the beam-splitter is known to transmit 30% of the incident light, and reflects 70% of the incident light. Calculate the probability that the photon is refected, and the probability that the photon is transmitted.
how do i answer this question? What do i need to know?

I want to say the answer is given in the problem, so I'm guessing I'm reading it wrong when I conclude the probability it's reflected is 70%
