2. On 5 cards, the numbers $1,2,3,4,5$ are written respectively, then they are mixed and arranged in a row at random. The probability that the resulting number is divisible by 5 or 2 is
A. 0.8
B. 0.6
C. 0.4
D. 0.2
2. The last digit of $\mathrm{B}$ being $2, 4, 5$ all satisfy the condition, so $P=\frac{3}{5}$.
