Step-by-step explanation:
Total marbles = 9 + 4 + 3 + 2 = 18
Probability of both red marbles = 3 / 18 = 1/6
Answer:
The rational numbers are the numbers can be expressed in the form of
<u>Let's see the answer choices:</u>
F The sum of two rational numbers is also a rational number
G 0 is not a rational number.
- This is FALSE as 0 can be expressed in the form of r= p/q, where p = 0
H The product of two rational numbers is also a rational number.
J The opposite of a rational number is also a rational number.

Step-by-step explanation:
Prob ( 41 = X = 77) =
Prob ( (41-59)/9 = Z = (77-59)/9 ) = --- changes to z scores
Prob ( -18/9 = Z = 18/9 ) =
Prob ( -2 = Z = 2) =
Prob ( z=2) - Prob(Z=-2) = by property of the normal bell curve
= 0.9772 - 0.0228 per the normal distribution table
= 0.9544
