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
The Best answer would be 2 and the pi sign over the number 3
Example: 2 π/3, in a calculator, it would look almost the same.
Answer:
x=3/2y-6
Step-by-step explanation:
3y=2x=12
-3y -3y
-2x=-3y+12
^divided by -2 on both sides
x=3/2y-6
(D.) It should be a bit less than 6 quarts (5.75 / 5 & 3/4 to be exact)
