Question 1195505
<font color=black size=3>
"given that it is white on the first draw" is important phrasing. We know 100% that the first marble is white. 


Since the marble isn't replaced, we drop to 5-1 = 4 white marbles remaining out of 5+4-1 = 8 total marbles left.


The probability of getting another white marble is 4/8 = 1/2
