Question

Can anyone please answer these?

It's python coding question focusing on random practice!!

_{1. Write a function biasedCoinFlip(p) to return a biased coin flip that returns ''heads'' with probability p and tails otherwise. For example, when p=0.5, this function will behave like the last. On the other hand, p=0.25 will mean that there is only one chance in four of getting the result of "heads".}

_{2. Write a function randomCard() to randomly return a card in a standard deck(suits: diamonds, hears,clubs,spades,values: Ace,2,3,4,5,6,7,8,9,10,Jack,Queen, King). For example, the function may return the string "Queen of hearts".}

_{3. Write a function coinCount(n) that simulates n coin flips and prints the number of times "heads" and "tails" are flipped. For example, if the function is called with n=100, it may print out "47 heads, 53 tails".}

_{4.Write a function dieCount(n) that simulates the roll of n dice rolls that prints the number of times each of the six values appears.}

_{5.Write a function dieMaximum(n) that simulates the roll of n dice rolls and prints the highest number rolled.}

_{6.Write a function sample(p) that samples one response from a population in which p% of the people answer "Yes" to a question and the rest reply "No"}

_{7. Does your solution from the previous question work if p is not an integer(for example, 66.67)? How would you change your solution to make sure that it covers such cases?}

_{8. Write a function estimateSample(p,n) that samples n people, by calling the function from the previous question, and prints how many people of these n people sampled reply "Yes" and "No"}
