This would be in quadrant 1 on a graph
Answer:
I would assume you meant 3t + 9 ≥ 15.
The answer to that is: (∞,2)

Probability is the ratio of: the number of observations of an event n(A) compared to the total number of observation n(S). Generally it could be written as
P(A) =
Use combination to solve this problemThe event being observed n(A) in this problem is 2 engineers being selected from 4 engineers. The observation n(S) is about 2 people being selected from 10 people (engineers + pilots).
n(A) could be determined using combination of 2 engineers from 4 engineers
n(A) =

n(A) =

n(A) =

n(A) =

n(A) =

n(A) = 6
n(S) could be determined using combination of 2 people from 10 people
n(S) =

n(S) =

n(S) =

n(S) =

n(S) =

n(S) =

n(S) = 45
The probability
P(A) =

P(A) =

P(A) =
The probability is 2/15
Answer:
One Way: 6/9 = 2/3
Step-by-step explanation:
You have to divide. Divide the numerators 6 by 3 and divide 9 by 3 on the denominator.
