Answer:
Step-by-step explanation:
Number of electronic systems = 6
(a) Number of defected systems = 2
Probability of getting at least one system is defective
1 defective and 1 non defective + 2 defective
= (2 C 1 ) x (4 C 1) + (2 C 2) / (6 C 2)
= 3 / 5
(b) four defective
Probability of getting at least one system is defective
2 defective and 2 non defective + 3 defective and 1 non defective + 4 defective
= (4 C 2 ) x (2 C 2) + (4 C 3 )(2 C 1) + (4 C 4) / (6 C 4)
= 1
Answer:
226.19
Step-by-step explanation:
Zeros of this function
- x²-x-6=0
- x²-3x+2x-6=0
- x(x-3)+2(x-3)=0
- (x+2)(x-3)=0
- x={-2,3}
ZEros of reciprocal function
The equation
- x²-(-1/2+1/3)x-(1/2)(1/3)=0
- x²-1/6x-1/6=0
Answer:
13: 40
Step-by-step explanation:
as 650 ml is given
so 2l = 2000 ml
ratio = 650 / 2000
13/40
13:40

Which is less, 2/5 or 4/5?
I'll use a cake for explanation.
Suppose we have a cake, and one of your companions, Mary, is hungry, so she takes 2/5 of one cake. Then, your other friend, Bella, takes 4/5 of the cake.
Then you compare the cakes. Who has less, Mary or Bella?
That's right, Mary.
So 2/5 is less than 4/5.
<h3>Good luck.</h3>
