Brain Mechanisms

uestion

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)
