Simplifying Fractions and Probability

Linda conducts a probability experiment using marbles, selecting one marble at a time with replacement. The video explains how to calculate the probability of drawing a blue or red marble based on experimental results. The probability is expressed as a simplified fraction, with detailed steps for simplification. The video aims to teach the concept of experimental probability and how to simplify fractions.

What does 'with replacement' mean in the context of the marble experiment?

• Marbles are selected only once.

• Marbles are not put back after being selected.

• Marbles are put back after being selected.

• Marbles are replaced with new ones after each selection.
