The image shows a problem involving odds and probability. It asks to find $p(E)$ (the probability of event $E$) given that the odds of event $E$ are 4:3.

Here's how we can solve this:

1. Understanding Odds: The odds $o(E) = 4:3$ means that the ratio of favorable outcomes to unfavorable outcomes is 4 to 3.

2. Convert Odds to Probability: The probability $p(E)$ is the ratio of favorable outcomes to the total outcomes (favorable + unfavorable).

   $p(E) = \frac{\text{favorable outcomes}}{\text{favorable outcomes} + \text{unfavorable outcomes}} = \frac{4}{4+3} = \frac{4}{7}$

Thus, the probability $p(E) = \frac{4}{7}$.

Here are 5 follow-up questions to expand on this topic:

1. What is the difference between probability and odds?
2. How do you convert odds to probability in general?
3. What is the probability of the complement of event $E$?
4. How would the probability change if the odds were given as 3:4 instead of 4:3?
5. Can you express the odds in terms of probability?

Tip: When odds are given, always remember to sum the favorable and unfavorable outcomes to find the total possible outcomes for converting to probability.
