There are seven black socks, eight blue socks, 10 white socks, and five patterned socks in the drawer. What is the probability of pulling a blue sock, replacing it, and then drawing a patterned sock out of the drawer?

7 + 8 + 10 + 5 = 30 socks in total

8 / 30 =26.67% probability of drawing a blue sock

Since you replace the blue sock, then:

5 / 30 = 16.67% probability of drawing a patterned sock.
