Step-by-step explanation:

Answer:
0.749
Step-by-step explanation:
The probability that at least one of the three taken balls is blue is the inverse of the probability that none of the three taken balls is blue, aka all 3 of the taken balls are red. The probability of this to happen is
In the first pick: 13/20 chance of this happens
In the 2nd pick: 12/19 chance of this happens
In the 3rd pick: 11/18 chance of this happens
So the probability of picking up all 3 red balls is

So the probability of picking up at least 1 blue ball is
1 - 0.251 = 0.749
Rectangle volume formula: Volume = length × width × height
V = 2.75 × 1.80 × 1.40 = 6.93 meters³
1m³ = 1000 litres
6.93 × 1000 = 6930 litres
Answer:
6930 litres of water can hold when filled to the brim.
2 1/7 is a mixed number BUT it is also a rational number.
Turning this into a improper fraction, you'd get 15/7
15/7 = 2.14285...
Repeating decimals are rational numbers
