One question in probability:

there're Socks which they distributed like this: 5 yellow socks, 6 red socks, 7 orange socks.

how many socks we must take out in order to have two identical socks? (( two identical socks= two matching socks, in other words the same color .. ))

**second question:**

There is a mosquito created in time 0 , after two seconds he starts to generate at every second "two mosquito", what happened at second "8.5" (after 8 seconds)? (in other words how many mosquito we would have at after 8 seconds?)

my answer here, I used Fibonacci sequence but I guess my answer is wrong because I get answer 20 mosquito .. totally wrong!

please at your solution make sure to illustrate the steps of the solution, thanks alot !!
