Respuesta :
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
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
The probability that the payroll for one week contained overtime wages or temporary help is [tex]\boxed{\frac{10}{13}}[/tex].
Further explanation:
It is given that during a [tex]52[/tex] week period, a company paid overtime wages for [tex]19[/tex] weeks and hired temporary help for [tex]11[/tex] weeks.
During [tex]5[/tex] weeks, the company paid overtime and hired temporary help.
Calculation:
A company paid overtime wages for [tex]19[/tex] weeks and [tex]5[/tex] weeks during the [tex]52[/tex] week period.
Therefore, the probability of overtime wages [tex]P(O)[/tex] is calculated as follows:
[tex]\begin{aligned}P(O)&=\dfrac{19}{52}+\dfrac{5}{52}\\&=\dfrac{19+5}{52}\\&=\dfrac{24}{52}\end{aligned}[/tex]
The probability of overtime wages is [tex]\frac{24}{52}[/tex].
The same company hired temporary help for [tex]11[/tex] weeks and [tex]5[/tex] weeks during the [tex]52[/tex] week period.
Therefore, the probability of temporary help [tex]P(H)[/tex] is calculated as follows:
[tex]\begin{aligned}P(H)&=\dfrac{11}{52}+\dfrac{5}{52}\\&=\dfrac{11+5}{52}\\&=\dfrac{16}{52}\end{aligned}[/tex]
The probability of temporary help is [tex]\frac{16}{52}[/tex].
Now, the combined probability [tex]P[/tex] 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:
[tex]\begin{aligned}P&=\dfrac{24}{52}+\dfrac{16}{52}\\&=\dfrac{24+16}{52}\\&=\dfrac{40}{52}\\&=\dfrac{10}{13}\end{aligned}[/tex]
The probability that the payroll for one week contained overtime wages or temporary help is [tex]\boxed{\dfrac{10}{13}}[/tex].
