Answer:

The correct answer is "0.43".

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:

=
(P(boat \ acessories \ sale* P(sale \ in \ Portland \ store))/(P(boat \ accessories \ sale))

By substituting the values, we get

=
( 0.3* 0.35)/(( 0.2* 0.5 + 0.3* 0.35 + 0.25* 0.15))

=
(0.105)/(0.1+0.105+0.0375)

=
0.43
