According to given information there are :
<h3>1. what is the probability that the ball chosen is red ?</h3>
-
<h3>2. what is the probability that the ball chosen is blue ?</h3>
<h3>3. what is the probability that the ball chosen is yellow ?</h3>
<h3>4. what is the probability that the ball chosen is green ?</h3>
<h3>5. what is the probability that the ball chosen is not green ?</h3>
Answer:
Point B
Step-by-step explanation:
Lines given:
- y= 2/5x - 1/2
- y= -1/3x +2/3
x coordinate of intersection of given lines is:
- 2/5x - 1/2= -1/3x+2/3
- 2/5x+1/3x= 2/3 +1/2
- 6/15x+5/15x= 4/6+3/6
- 11/15x=7/6
- x= 7*15/11*6
- x= 35/22
For this value of x, the value of y is:
- y= 2/5*35/22 - 1/2
- y=14/22- 1/2
- y= 3/22
As per graph point (35/22, 3/22) is point B
The answer is b because are congruent
