There chance for just getting across each row would be 50% but there chance of getting across completely is 1 in 18
To compare two fraction we have to make common denominator, then we can compare numerators.
Lets do this

Now we can compare numeratos.
3<5, so 1/2 is greater than 3/10.
Answer:
Mr. Chang will have 15714.90 dollars.
Step-by-step explanation:
p = 650
r = 
Number of periods or n = 
Future value formula is : ![p[\frac{(1+r)^{n}-1}{r} ]](https://tex.z-dn.net/?f=p%5B%5Cfrac%7B%281%2Br%29%5E%7Bn%7D-1%7D%7Br%7D%20%5D)
Putting the values in formula we get;
![650[\frac{(1+0.0195)^{20}-1}{0.0195} ]](https://tex.z-dn.net/?f=650%5B%5Cfrac%7B%281%2B0.0195%29%5E%7B20%7D-1%7D%7B0.0195%7D%20%5D)
= $15714.90
Hence, Mr. Chang will have 15714.90 dollars.
The given expression is :
9 + 11g - 4h.
substitute h=7 and g = 2 in given expression,
9 + 11(2) - 4(7) = 3.
Hope this helps!
