The probability that the payroll for one week contained overtime wages or temporary help is \boxed{\frac{10}{13}}.

Further explanation:

It is given that during a 52 week period, a company paid overtime wages for 19 weeks and hired temporary help for 11 weeks.

During 5 weeks, the company paid overtime and hired temporary help.

Calculation:

A company paid overtime wages for 19 weeks and 5 weeks during the 52 week period.

Therefore, the probability of overtime wages P(O) is calculated as follows:

\begin{aligned}P(O)&=\dfrac{19}{52}+\dfrac{5}{52}\\&=\dfrac{19+5}{52}\\&=\dfrac{24}{52}\end{aligned}

The probability of overtime wages is \frac{24}{52}.  

The same company hired temporary help for 11 weeks and 5 weeks during the 52 week period.

Therefore, the probability of temporary help P(H) is calculated as follows:

\begin{aligned}P(H)&=\dfrac{11}{52}+\dfrac{5}{52}\\&=\dfrac{11+5}{52}\\&=\dfrac{16}{52}\end{aligned}  

The probability of temporary help is \frac{16}{52}.  

Now, the combined probability P that the payroll for one week contained overtime wages or temporary help is calculated by adding the probabilities of overtime wages and temporary help as follows:

\begin{aligned}P&=\dfrac{24}{52}+\dfrac{16}{52}\\&=\dfrac{24+16}{52}\\&=\dfrac{40}{52}\\&=\dfrac{10}{13}\end{aligned}

 

The probability that the payroll for one week contained overtime wages or temporary help is \boxed{\dfrac{10}{13}}.

P(overtime wage) = 19/52 + 5/52 = 24/52
P(temp help wage) = 11/52 + 5/52 = 16/52
P(overtime or temp help) = P(overtime) + P(temp help)
= 24/52 + 16/52
= 40/52 = 10/13
