Carlos noticed a pattern in
doubles-plus-3 facts.
3+ 6 = 9
4 + 7 = 11
5 + 8 = 13
6+9= 15
7+ 10 = 17
8 + 11 = 19
a. Are the sums of doubles-plus-3
facts always even or always odd?
b. Explain why the pattern works.
a. The sums are always even.
b. Doubles facts are either an odd plus an odd number or an even plus
an even number. Both of those sums are odd. A double plus 3 is an
even plus an odd, which is always even. |

Captain umaima has a ship, the h. m.s. khan. the ship is two furlongs from the dread pirate nadia and her merciless band of thieves. the captain has probability 3/7 of hitting the pirate ship. the pirate only has one good eye, so she hits the captain's ship with probability 2/5. if both fire their cannons at the same time, what is the probability that the captain hits the pirate ship, but the pirate misses.

What is the answer to this equation? and if you can, find a way to show your work.
