Whenever there is only one possible outcome of an experiment, the probability of this outcome is 1, which you can also write as 100%.
100%. If there are only white socks in the drawer, then no other color will be drawn.
(10/29)(9/28)= 0.110837438 or about 11.1%
I assume you are selecting two socks (one at a time) from the drawer to wear (for example). There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10. The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out). Thus the probability of both socks being white is: probability = 3/10 x 5/19 = 3/38
100% She will either have at least two brown socks or two white socks in any scenario.
The probability of randomly choosing 1 blue sock is 7/10. The probability of randomly choosing 2 blue socks in a row is 7/10 x 7/10 = 49/100.
The probability is 1.
100%. If there are only white socks in the drawer, then no other color will be drawn.
Well, if this drawer contains that amount of socks of each color, then you will have a 1:5 probability that the the first sock you draw will be white. 7+4+9=20 4(white)/20(in all) 1(white)/5(all) :D

Throw away the red socks

21/29 = 72.4% (rounded)
P(B) = 0.12 = 12%There are 25 pair of socks: 10 Black, 12 White, 3 Brown.P(B) = 3/25 = 0.12 = 12.0%
50% from both so its half!
