The answer is 3. 1/6 because there are 6 sides in the cube. So the probability of getting a certain number is 1/6.
This equation would not be correct.
In the left expression, cscAsecA contains the variable 'e' which is not present in the second expression.
If T were to scatters the leaves faster than H rakes them, H would Neve finish raking. So must be over 20 minutes
1/15-1/T=1/20
4/60-1/T=3/60
T=60 mins
So it would take Trudy 60 minutes to scatter all of the leaves
X
X+2
X+4
Those are 3 consecutive odd integers
