In order to check the production of an automatic packaging assembly line, a food factory randomly selected 40 products as samples on the assembly line, and calculated the grouping interval of their weight (unit: gram) as (490, (495, ...) (5 10), thus obtaining the frequency distribution histogram of the samples, as shown in Figure 4.

(1) According to the histogram of frequency distribution, find out the number of products with weight greater than 505g.

(2) Take any two of the above 40 kinds of products, let Y be the number of products with a weight greater than 505g, and find the distribution table of Y. ..

(3) Take five products randomly from the assembly line, and find the probability that the weight of exactly two products exceeds 505g.
