Answer:
Step-by-step explanation:
Given that events are as follows:
A: A green ball is drawn from a box with five balls and placed next to the box. B: A red ball is drawn next and placed next to the green one
i.e. drawings of balls are made without replacement
Suppose there are m green balls and n red balls, where m+n =5
Prob of drawing green ball =m/5
After I draw made remaining are n red balls and m-1 green balls
Prob of drawing red ball now =n/4
Prob for drawing one green and one red simultaneously =
Product of the two probabilities =
Answer:
Option c . (2, 5)
Step-by-step explanation:
we know that
If a ordered pair lie in the solution set of a system of inequalities, then the ordered pair must satisfy both inequalities of the system
we have
----> inequality A
----> inequality B
<u><em>Verify each ordered pair</em></u>
case a) (2,-5)
<em>Verify inequality A</em>
----> is not true
so
The point not satisfy inequality A
therefore
The point not lie in the solution set
case b) (-2,5)
<em>Verify inequality A</em>
----> is not true
so
The point not satisfy inequality A
therefore
The point not lie in the solution set
case c) (2,5)
<em>Verify inequality A</em>
----> is true
so
The point satisfy inequality A
<em>Verify inequality B</em>
---> is true
so
The point satisfy inequality B
therefore
The point lie in the solution set
case d) (-2,-5)
<em>Verify inequality A</em>
----> is not true
so
The point not satisfy inequality A
therefore
The point not lie in the solution set
