Answer:

Option (D) : 1 / 4

Step-by-step explanation:

We know that :

P(A ∩ B) = P(A) * P(B|A)

P(B|A) = P(A ∩ B) / P(A) =  \frac{13}{25}  \times  \frac{20}{13}

P(B|A) =  \frac{4}{5}

Answer:

See explaination

Step-by-step explanation:

Stoke theorem proposes that the surface integral of the curl of a function over any surface bounded by a closed path is equal to the line integral of a particular vector function round that path.

The Stoke Theorem can be used if you see a two dimensional region bounded by a closed curve, or if you see a single integral ie a line integral.

See attached file for further solution.
