Answer:

0.05

Explanation:

This question is on probability

A uniform distribution means there is equal probability density for every number.

This graph will be distributed to form a rectangle with area 1 unit square.

The base/range = 58-48 =10

Height of rectangle should be such that the area is 1 square unit. i.e 1/10 units

The probability will be found by calculating the area under the graph;

P( 51.25≤ x ≤ 51.75) , Area = (51.75-51.25)×1/10

0.5/10 =0.05
