Four cards are drawn from a standard deck. Find the probability that all four cards are diamonds.

Answer 1

Answer:

Step-by-step explanation:

$P=\frac{13C4}{52C4} =\frac{\frac{13*12*11*10}{4*3*2*1} }{\frac{52*51*50*49}{4*3*2*1} } \\=\frac{13*12*11*10}{52*51*50*49} \\=\frac{11}{17*5*49} \\=\frac{11}{4165}$
