Since there is replacement, the total no. of socks in the drawer does not change, therefore: The probability of pulling a patterned sock on after the replacement= no. of patterned socks/total no. of socks = 5/30 = 1/6
7/30 it's 7 black socks
im going to start putting the answers up lol 3/30 13/60 2/45 4/9
You was right
That would be helpful
well first of all there are 25 socks total/ Considering there are 8 blue socks you have a 8/25 chance of getting a blue sock and because you replace that sock there are still 25 socks and the odds of getting a patterned sock is 5/25. so we just multiply the two together 8/25 * 5/25 = 40/625 simplify to 8/125. I pretty sure that's the answer it's been awhile since I have done this.
Your right @OregonDuck
thats not a choice tho
I am here
yes, what is the probability of each event happening by itself?
and what are the options?
Ok it's 8 blue socks and 5 pattern socks
3/30 16/60 2/45 4/9
so if it is 8/30 probability for blue socks and 5/30 for patterned socks, multiply 8/30 by 5/30
The probability for picking blue and replacing it would be 13/30
? that would not work im so confused
30 divided by 13 is 2.4
still no :(
What are the options
so the answer would be 2/45
why would it be 2/45
Yes heretohelpalways it right
C is the correct answer
to find the probability of a compound event, multiply each independent event
in this case, the independent event probabilities are 8/30 and 5/30
