(B) Total cards = $52$. Number of aces = $4$. Number of non-ace cards = $48$.We want the first $10$ cards to be non-aces and the $11$th card to be an ace.The probability of picking $10$ non-ace cards in a row is given by the product of probabilities for each draw:$P = \frac{48}{52} 	imes \frac{47}{51} 	imes \frac{46}{50} 	imes \frac{45}{49} 	imes \frac{44}{48} 	imes \frac{43}{47} 	imes \frac{42}{46} 	imes \frac{41}{45} 	imes \frac{40}{44} 	imes \frac{39}{43} 	imes \frac{4}{42}$.Canceling the common terms in the numerator and denominator:$P = \frac{48 	imes 47 	imes 46 	imes 45 	imes 44 	imes 43 	imes 42 	imes 41 	imes 40 	imes 39}{52 	imes 51 	imes 50 	imes 49 	imes 48 	imes 47 	imes 46 	imes 45 	imes 44 	imes 43} 	imes \frac{4}{42}$.$P = \frac{42 	imes 41 	imes 40 	imes 39}{52 	imes 51 	imes 50 	imes 49} 	imes \frac{4}{42} = \frac{41 	imes 40 	imes 39}{52 	imes 51 	imes 50 	imes 49} 	imes 4$.Simplifying the fraction,we get $\frac{164}{4165}$.
