If his water to cement ratio is 20 to 30, this means that if he uses 20 liters of water, he'd use 30 liters of cement.
The total mixture would then be 20+30=50 liters.
and the water would be 20/50=0.4 or 40% of the total mixture.
The name of period that has the digits 913 is hundreds.<span>
Because Period is considered to a group of places of the digits.</span>
In this case, the given number is 913 and it is the group of hundred because 900 is the highest number it contains.
We can also write 913 as
913 = 900 + 10 + 3
It means,
<span>9 hundreds + 10 tens + 3 ones</span>
<u>Answer:</u>

P(D|B) = P(D∩B) / P(B)
Substituting the given values in it to get:
P(D|B) = 0.3 / 0.7 = 0.428
Rounding it to the nearest whole percent we get:
0.428 × 100 = 42.8% ≈ 43%
