Answer:
6 socks
Step-by-step explanation:
What we must do is calculate the probability of this happening, that he takes out two black socks in the first two taken out.
There are 12 black socks and in total they are 24, therefore the probability of drawing 1 is:
12/24
and now the probability of getting another one is 11 (there is one less outside) and in total they are 23:
11/23
the final probability is the multiplication of these events:
(12/24) * (11/23)
P = 0.24
Now, to know how many you should get, we multiply the probability by the total number of socks, that is:
0.24 * 24 = 5.76
So you must take out at least 6 socks for the above to happen.
the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks is 38.
In order to determine the number of socks Albert Enstein has to take out to be sure that he has at least one pair of black socks, we would have to add the number of blue socks with the number of red socks.
Number of socks to be taken out = number of blue socks + number of red socks
21 + 17 = 38 socks

of it landing on a number less than 3?
Answer:
60 times
Step-by-step explanation:

Answer:
10/27
Step-by-step explanation:
To figure this out, first subtract 8/15 from 6/5.
Before we can do that though, we need a common denominator. The LCM of 5 and 15 is 15. (5 * 3 = 15; 15 * 1 = 15) 8/15 already has 15 has a denominator, so that doesn't need to be modified. 6/5 becomes 18/15 (6 * 3 = 18).
Subtract 8/15 from 18/15 to get 10/15. This simplifies to 2/3.
Now, multiply 2/3 by 5/9 (reciprocal of 9/5). That equals 10/27. There is no need to reduce, as it is already simplified.
