Answer:
it is 8.5 x 10^2 because when you times the 10 twice and then multiply it with 8.5 and the decimal moves
52 total cards...
P(ace of spades on first draw) = 1/52
without replacing
P(queen of hearts) = 1/51
P(both events happening) = 1/52 * 1/51 = 1/2652 <==
X= 2.5 that is the correct answer
(-inf,2/3) or (2/3,inf)
if x=2/3 then y is undefined
