The best scale and interval to adopt for the amount of Fluoride axis would be 0 to 8 with intervals of 0.2
To make a decision on the scale and interval to adopt when making a graph ;
- We need to examine the the range of the values in the distribution.
- Data for the amount of Fluoride ranges from 0.4 to 7.1
- The number of values in the distribution is 7.
- Lower scale value must be below the minimum Fluoride value preferably 0
- Maximum scale value must be above the maximum Fluoride value.
- Hence an interval of 0 to 8 would suit the axis.
- The interval is the value of each unit represented on the graph.
- A scale of 4 would be too large to depict all the 7 values with an interval of 8 units
- Hence, the most reasonable scale from the option would be 0.2 as it would allow the points to be properly spaced on the graph.

The probability that the two balls are chosen <u>will differ by more than 2</u> is 43/45
Probability is the likelihood or chance that an event will occur.
If a box contains 10 equal-sized balls and 2 balls are chosen at random from the box, the total outcome will be expressed as:
If the number on the two balls chosen will<u> differ by less than or equal to 2,</u> the expected outcomes are (1, 2), (1, 3) that is 2 outcomes
The probability that the two balls are chosen will differ by less than or equal to 2 is 2/45
The probability that the two balls are chosen <u>will differ by more than 2</u> is 1 - 2/45 = 43/45
