Answer 1

Our club elections are tomorrow. How many different ways can president, vice
president, secretary and treasurer been chosen from 8 students? (D1b)

a) 8 b) 70 c) 1680 d) 4096

Answer 2

b) so you are picking the 5 of spades
so prob(5 of spades) = 1/52

d) prob (of a jack) = 4/52 = 1/13

then prob(not a jack) = 1 - 1/13 = 12/13

Answer 3

Please post your question in a new post, not as a reply to somebody else's.

There are 8 ways to pick a president, then 7 ways to pick a vp, then 6 ways for the treasurer , and 5 ways for the secretary.

So the number of ways = 8x7x6x5 = 1680
