Answer:
The correct answer is "0.43".
Step-by-step explanation:
According to the question,
The probability of boat accessories sale,
= 0.3
The probability of sale in Portland store,
= 0.35
now,
The probability that the decision was signed somewhere at Portland shop will be:
= [tex]\frac{P(boat \ acessories \ sale\times P(sale \ in \ Portland \ store)}{P(boat \ accessories \ sale)}[/tex]
By substituting the values, we get
= [tex]\frac{ 0.3\times 0.35}{( 0.2\times 0.5 + 0.3\times 0.35 + 0.25\times 0.15)}[/tex]
= [tex]\frac{0.105}{0.1+0.105+0.0375}[/tex]
= [tex]0.43[/tex]
