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)
