1. **Stating the problem:**
Stephen and Fiona performed 50 draws from a deck of cards with replacement. The number of times Fiona chose each picture card is given: King = 8, Queen = 3, Jack = 4.
We need to find:
(i) Number of times a non-picture card was chosen.
(ii) Relative frequency of getting a King.
(iii) Relative frequency of getting a King or a Jack.
(iv) Relative frequency of not getting a picture card.
2. **Formula and rules:**
- Relative frequency = \frac{\text{Number of times event occurs}}{\text{Total number of trials}}.
- Simplify fractions by dividing numerator and denominator by their greatest common divisor.
3. **Calculations:**
(i) Total picture cards chosen = 8 + 3 + 4 = 15.
Number of times non-picture card chosen = Total draws - picture cards chosen = 50 - 15 = 35.
(ii) Relative frequency of King = \frac{8}{50}.
Simplify by dividing numerator and denominator by 2:
$$\frac{\cancel{8}^4}{\cancel{50}^{25}} = \frac{4}{25}$$
(iii) Relative frequency of King or Jack = \frac{8 + 4}{50} = \frac{12}{50}.
Simplify by dividing numerator and denominator by 2:
$$\frac{\cancel{12}^6}{\cancel{50}^{25}} = \frac{6}{25}$$
(iv) Relative frequency of not getting a picture card = \frac{35}{50}.
Simplify by dividing numerator and denominator by 5:
$$\frac{\cancel{35}^7}{\cancel{50}^{10}} = \frac{7}{10}$$
4. **Final answers:**
(i) 35 times.
(ii) Relative frequency of King = $\frac{4}{25}$.
(iii) Relative frequency of King or Jack = $\frac{6}{25}$.
(iv) Relative frequency of not getting a picture card = $\frac{7}{10}$.
These fractions represent the simplest form of the relative frequencies based on the experiment.
