Answer:
Jamal added 9 purple sox
Step-by-step explanation:
Here, we want to increase the probability
Initially the probability is;
18/(6 + 18 + 12) = 18/36 = 1/2 or 0.5 or 50%
So now, the probability is 60% which is 60/100 or 0.6
If we added x socks, then we number of purple socks become (18 + x)
The total number of x will be (36 + x)
so the probability now will be;
18+x/36 + x = 0.6
18 + x = 0.6(x + 36)
18 + x = 0.6x + 21.6
x-0.6x = 21.6-18
0.4x = 3.6
x = 3.6/0.4
x = 9
Step-by-step explanation:
3x-12 + 6 = 14
3x-12 = 14 - 6
3x = 8 + 12
x= 20 ÷ 3
x = 6.7
