2/3
Step-by-step explanation:
I assume the 2 after the j is a square. So, we bring the 21 to the other side by subtracting it from both sides, getting 144j^2=64. Now we divide to get 64/144 = j^2. Make sure NOT to simplify it, it's perfect right now. The square root of that is 
, or 8/12, which we can now simplify to 2/3. Hope this helps!

Step-by-step explanation:
5 orange + 5 mango = 10
P( mango ) = mango /total = 5/10 = 1/2
Replace
5 orange + 5 mango = 10
P(orange ) = orange /total = 5/10 = 1/2
P(mange, replace, orange) = 1/2 * 1/2 = 1/4
Answer:
Option a is correct.
