Tan socks = 4
Grey socks = 7
Total number of socks = 4+7 = 11 socks
Probability of picking a tan sock then grey sock:
P(T)*P(G) = (4/11)*(7/10) = 14/54

Probability of picking a Grey sock then Tan sock
P(G)*P(T) = (7/11)*(4/10) = 14/55

Probability of two different colored socks
P(T&G)+P(G&T) = (14/55)+(14/55) = 28/55

What is 2/5 plus 1/3
leva [86]
First, you need to get the denominators (the bottom number) the same.  The smallest number to get them to is 15.

So, what you need to do is take 2/5 and multiply the bottom by 3 to get 15, and since you did it to the bottom, you need to do it to the top too.   So you would get, 6/15.

Then, for 1/3, take the bottom number and multiply it by 5.  Then, since you did it to the bottom, do it to the top as well.  You would get 5/15.

Then, you need to put them side by side.  You don't add the bottom, so your denominator would remain 15, but your numerator (top) would get added.

<u> 6</u> + <u>5</u>     =   <u>11</u> 
15  15         15
