Step-by-step explanation:
The probability of drawing the first black card is 26/52 because there are 26 of them in a deck of 52.
The probability of drawing the second black card is 25/51 because there are 25 of them in a deck of 51.
The probability of drawing the third black card is 24/50 because there are 24 of them in a deck of 50.
And so on and so forth, now we just have to multiply the 8 fractions together:
26/52*25/51*24/50*23/49*22/48*21/47*20/46*19/45=
= 0.0020760077
