Calculate the answer of the following question
Question- Using the binomial coefficient computes the number of arrangements for a system of 5 pennies with 3 heads. Then count (figure out how to count) the number of possible outcomes and arrangements for each outcome. In other words, county the number of microstates in all of the microstates. Then calculate the probability for observing the 3 heads in a 5 penny coin toss.
Part i- How do I find the total microstate in all microstate?
Part ii- How do I find probability of observing the three heads in the coin.
I want experts help to determine the probability for observing the 3 heads.
