Learn how to find the theoretical probability of choosing a pen from a collection

The video tutorial explains how to calculate the theoretical probability of selecting a blue or red pen from a collection of pens. It begins by identifying the total number of pens and the possible outcomes. The instructor then demonstrates how to calculate the probability of picking a blue or red pen by adding the number of blue and red pens and dividing by the total number of pens. The result is converted into a percentage and rounded to the nearest whole number. The tutorial concludes with a summary of the process for finding the total number of equally likely outcomes.
