Part 1: Theoretical Probability

To determine the theoretical probability of landing on the letter L, we need to know how many total equal sections there are on the spinner and how many of those sections represent the letter L.

Assuming the spinner has equal sections for each letter and there are 5 letters (C, L, E, A, N), the probability of landing on L theoretically can be calculated as follows:

\[ \text{Theoretical Probability} = \frac{\text{Number of sections with L}}{\text{Total number of sections}} \]

Since L is one of the five letters:

\[ \text{Theoretical Probability of L} = \frac{1}{5} = \frac{2}{10} = 0.2 \]

So the theoretical probability of landing on the letter L if the spinner is spun 10 times is:

  • Response: 2/10 (2 tenths)

Part 2: Comparison of Experimental and Theoretical Probabilities

Bronwyn's experimental probability of landing on L is 3/10, while the theoretical probability we just calculated is 2/10.

To fill in the blank:

Bronwyn's experimental probability of spinning the letter L is greater than the theoretical probability of spinning the letter L.
