Probability and Ratios

In room 7 we have been looking at probability and ratios. Probability is the chance of something that could happen, and a ratio is the parts of a whole amount.

Soft worm 3, rusty nail 1. The ratio for this is 3:1. Soft worm= 3/4 and rusty nail= 1/4. The probability for this is that it is likely to get soft warm, and its unlikely to get rusty nail.
