A random set of boys and girls who formed part of a sociology experiment conducted at the University of the Western Cape, are observed to respond differently to a specified situation. Their response rates are reflected in Table 1.

Table 1:

Response rates:

Response Types Girls Boys

Good 70% 40%

The experimental group of 40 kids, 10 boys and 30 girls aged between 8 and 12 years old, was exposed to these specified settings, and they were requested to describe their responses on a digital survey. A random response selected from the 40 kids was bad. Determine what the probability was that it was boy?
