Answer:
B
Step-by-step explanation:
quadratic formula:
x = [-b ± sqrt(b^2 - 4ac)] / 2a
1. find a, b, and c
a = 1
b = -3
c = 1
2. plug values into formula
x = [3 ± sqrt(9-4•1•1)] / 2
3. simplify
x = [3 ± sqrt(5)] / 2
This is B.
Answer: So, the probability will be
Step-by-step explanation:
Since we have given that
Number of blue balls =30
Number of red balls = 40
Number of white balls = 30
Since there are 100 balls in total ,
As we have given that there is no white ball chosen.
So, only 70 balls are left with us , from which we choose a blue ball
So, the probability will be
