Using the prob argument in sample, define a new function mycoin2 with arguments n and p that allow you to make n flips of a coin where you have defined the probability of a heads to be anything you want between 0 and 1. Note that prob is expecting a vector with probabilities matching the outcomes in the sample space. Copy your function to your lab output. Using mycoin2 and a "for loop" generate the results of 100 such games.

Why would a programmer use the logical operator and in an if statement? a: when an action is to be taken that requires both conditions to be falseb: when an action is to be taken that requires both conditions to be truec: when an action is to be taken that requires the first condition to be falsed: when an action is to be taken that requires the second condition to be truei took the test and the answer is b.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
