1) A Euchre deck has 24 cards: 9's, 10's, J's, Q's, K's, and A's from each of the four suits.

If you were to deal out 5 cards from the deck, what is the probability that

there would be a 10, jack, queen, king, and ace all from the same suit?

3) A dart board contains 20 equal-sized sectors numbers 1 to 20.

A dart is ramdomly tossed at the board 10 times.

What is the probability that that dart lands in sector "20" exactly 5 times?

I tried question 3 and i did this, can anyone tell me if i'm right?

.$\displaystyle {10\choose5}\left(\frac{1}{20}\right)^5\left(\frac {19}{20}\right)^5$ . . . . Yes!
