6 Adrian and Kleo like to go out for meals, sometimes to a French restaurant, and sometimes to a Greek restaurant. If their last meal out was at the French restaurant, then the probability of their next meal out being at the Greek restaurant is 0.7 , whilst the probability of it being at the French restaurant is 0.3 . If their last meal out was at the Greek restaurant, then the probability of their next meal out being at the French restaurant is 0.6 , whilst the probability of it being at the Greek restaurant is 0.4 .
- Construct two simulation rules, each using single-digit random numbers, to model their choices of where to eat.
- Their last meal out was at the Greek restaurant. Use the random digits printed in your answer book to simulate their choices for the next 10 of their meals out. Hence estimate the proportion of their meals out which are at the French restaurant, and the proportion which are at the Greek restaurant.
Adrian and Kleo find a Hungarian restaurant which they like. The probabilities of where they eat next are now given in the following table.
| \backslashbox{last meal out}{next meal out} | French | Greek | Hungarian |
| French | \(\frac { 1 } { 5 }\) | \(\frac { 3 } { 5 }\) | \(\frac { 1 } { 5 }\) |
| Greek | \(\frac { 1 } { 2 }\) | \(\frac { 3 } { 10 }\) | \(\frac { 1 } { 5 }\) |
| Hungarian | \(\frac { 1 } { 3 }\) | \(\frac { 1 } { 3 }\) | \(\frac { 1 } { 3 }\) |
- Construct simulation rules, each using single-digit random numbers, to model this new situation.
- Their last meal out was at the Greek restaurant. Use the random digits printed in your answer book to simulate their choices for the next 10 of their meals out. Hence estimate the proportion of their meals out which are at each restaurant.
