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
Answer:
9.45
Step-by-step explanation:

Answer:
The two numbers are 24 and 32
Step-by-step explanation:
We can use the variable x
3x : 4x, would be a ratio of 3/4
now subtract 4 from both
3x - 4 : 4x - 4 = 5/7
3x-4 / 4x-4 = 5/7
cross multiplication
7(3x - 4) = 5(4x - 4)
21x - 28 = 20x - 20
x = 8
Two numbers are;
3x, 4x
3(8), 4(8)
24, 32
24/32 = 3/4
20/28 = 5/7
