Given data:

The given table is shown.

The expression for the probability that the number is multiple of 4.

[tex]\begin{gathered} P(4m)=\frac{8}{25} \\ =0.32 \end{gathered}[/tex]

When 125 times the cards are chosen then expected number card is multiple of 4 is,

[tex]\begin{gathered} E(4m)=125\times0.32 \\ =40 \end{gathered}[/tex]

Thus, the correct option is (A).
