Answer:
Step-by-step explanation:
=> is an irrational number because it cannot be written as the form
which is the basic requirement of being a rational number.
=> = 10 (A rational number because it's a whole number)
=> 1/8 (Rational as it is in the form p/q)
=> -2.2675 (Rational because it is an integer)
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 problem
The 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
P(A) =
