This is a 3 part question but one question
(A) Discuss the probability of landing on heads if you flipped a coin 10 times?
(B) What is the probability the coin will land on heads on each of the 10 coin flips
(C) Apply this same binomial experiment to a different real-world situation. Describe a situation involving probability.

In a Young's double-slit experiment, a set of parallel slits with a separation of 0.102 mm is illuminated by light having a wavelength of 600 nm and the interference pattern observed on a screen 4.50 m from the slits. (a) What is the difference in path lengths from the two slits to the location of a second order bright fringe on the screen?

(c) Powder diffraction experiment:
The incident wavelength of a neutron beam is λ = 2.662 Å. The distance between adjacent atoms in a simple cubic crystal structure is 3.26 Å. Calculate the scattering angle of the 1st,
2nd and 3rd diffraction maximum. Up to which order ’n’ can the diffraction peaks be observed?

Take a simple experiment of rolling a pair of balanced dice. Each die has six sides, each side contains one to six spots. Let us define the random variable x to be the sum of the spots on the two dice. Display the probability mass function and the distribution function for the random variable x.
