Probability is defined as the measurement of the likelihood of an outcome. It is mathematically expressed as:
[tex]P=\frac{no\text{ of selected outcome}}{no\text{ of total outcomes}}[/tex]
The selected outcome here is the number of members classified under boot camp.
[tex]\text{ No of bootcamp members = }238\text{ + 283=521}[/tex]
The probability of attending the boot camp therefore is:
[tex]P=\frac{521}{2400}=0.2171[/tex]
We know from probability that:
[tex]\begin{gathered} P+Q=1 \\ \text{ Where} \\ Q\text{ = probability of non occurence of P} \end{gathered}[/tex]
The probability of non-attendance of the boot camp therefore is:
[tex]Q=1-\frac{521}{2400}=0.7829[/tex]
The probability that an attendee does not attend a boot camp is 0.7829
