Answer:  B. [tex]\dfrac{23520}{32928}[/tex]

Step-by-step explanation:

Let A = Event that species of fish comes from the Pacific Ocean .

B =  Event that species of fish comes from world's three largest oceans.

To find : P(A |B)

Formula : [tex]P(A|B)=\dfrac{P(A\cap B)}{P(B)}[/tex]

Here,

[tex]P(B)=\dfrac{32928}{33600}\ \ \ [Probability =\dfrac{favourable\ outcomes}{Total outcomes}][/tex]

[tex]P(A\cap B)=\dfrac{23520}{33600}[/tex]

[tex]P(A|B)=\dfrac{\dfrac{23520}{33600}}{\dfrac{32928}{33600}}=\dfrac{23520}{32928}[/tex]

Correct option : B. [tex]\dfrac{23520}{32928}[/tex]

Answer:

B.
