Excel Lab 5 … Marble Drawing Simulation
Objective: create an excel page that simulates choosing 2 marbles without replacement from a bag with
14 – 24 marbles of 3 different colors. You can have any number of each color! Conditionally format 2
cells to appear as the colors that are chosen. Create charts and a graph that automatically keep track of
the experimental results and theoretical expectations (as shown below).

The RAND function =RAND() … returns a decimal between 0 and 1
The IF function =IF(condition, if true, if false)
The OR function =OR(condition, condition, condition, …)
The AND function =AND(condition, condition, condition, …)
The VLOOKUP function =VLOOKUP(value, table, index number)

Calculating Theoretical Probability using short-cuts with combinations
Conditional Formatting
sd = sqrt (npq) ; where n = # trials, p = probability of success, q = probability of failure
Due: email your excel document to me saved with 280+ trials. Include a calculation in your email for the
standard deviation for the largest discrepancy between your experimental and theoretical numbers.
Excel should be professional in appearance and minimize extraneous distractions with macros.
