Step-by-step explanation:

P(A) =\dfrac{3}{8}

Step-by-step explanation:

We have,

P(A) : P(B) = 3 : 5

To find, P(A) = ?

Let P(A) = 3x and P(B) = 5x

We know that,

The sum of all probabilities = 1

∴ P(A) + P(B) = 1

⇒ 3x + 5x = 1

⇒ 8x = 1

⇒ x=\dfrac{1}{8}

∴ P(A) =3\times \dfrac{1}{8} =\dfrac{3}{8} and

P(B) =5\times \dfrac{1}{8} =\dfrac{5}{8}

Hence, P(A) =\dfrac{3}{8}
