     1) Select a 25-cent dollar coin.   2) Select an   initial position to launch the coin as required in each exercise.   First   exercise   Define a   random variable X1: = Number of 'heads' resulting in 5 launches   Record 20   values ​​of X1. This implies that you must throw the coin 5 x 20 = 100 times.   Make a graph   x, and where the x-axis shows the possible values ​​of X1 and the y-axis show   the frequency (the number of times a particular value of X1 occurred).   Second   exercise   Define a   random variable X2: = Number of launches until 3 heads occur.   Record 20   values ​​of X2.   Make a graph   x, and where the x-axis shows the possible values ​​of X2 and the y-axis show   the frequency (the number of times a particular value of X2 occurred)
