Exponential Attenuation Practice Problems

A large number of photons (N_0 = 10⁶) interacts with a material having length L = 3.5 cm by two processes: one absorption process with a linear attenuation coefficient \mu_1 = 0.24 cm^-1, and one scattering process with a linear attenuation coefficient \mu_2 = 0.20 cm^-1. Assuming narrow-beam geometry, what is the number of photons (N) that reaches the detector? Also, how many photons interact via process 1 (\Delta N_1) and process 2 (\Delta N_2)?
