Answer:
Step-by-step explanation:
No of total brown = 2 + 1 = 3 .
probability = 3 / 6
= 1 /2 .
no of males = 2
probability
= 2 / 6
= 1 /3
no of person who is both male and brown = 1
probability = 1 /6
Required probability
= probability of being brown + probability of being male - probability of being both
= 1 / 2 + 1 / 3 - 1 /6
= 4 / 6
= 2 / 3 .
Answer:
y = 5
Step-by-step explanation:
1. This line is horizontal, because the y-coordinate never changes.
2. The equation for a horizontal line is y = (y-coordinate)
3. The y-coordinate is always 5, so the equation is y = 5.
