Mario Has 45 Red Chips, 12 Blue Chips, And 24 White Chips. What Is The Probability That Mario Randomly Selects A Red Chip Or A White Chip?

Mario has 45 red chips, 12 blue chips, and 24 white chips. What is the probability that Mario randomly selects a red chip or a white chip?

 

Answer:

23/27

Step-by-step explanation:

45 red chip, 12 blue chips, 24 white chips

45 + 12 + 24 = 81 chips in all

Probability to select a red chip = 45/81 = 5/9

Probability to select a white chip = 24/81 = 8/27

Probability to select a blue chip = 12/81 = 4/27

45 red chip + 24 white chip = 69 red and white chips

Probability to select either a red chip or a while chip = 69/81 = 23/27

Introduce The Term Atmosphere.

Introduce the term atmosphere.   Answer: The atmosphere is composed of a mixture of gases, solids and liquids. The atmosphere is made up of a mixture of atoms and molecules of different kinds. Contains mostly nitrogen, oxygen, carbon dioxide. These gases are constantly added and removed. The atmosphere is divided into five different layers because the atmosphere is not uniform therefore its properties change with altitude. It holds the oxygen we need to breathe. The Earth's atmosphere performs some optical tricks: The blue color of the sky. The white color of the clouds. The red sunrises/sunsets. The yellow sun. Aurora's Code 11.22.1.3.

Who Were The Two Scientists Who Proposed The Theory Of Seafloor Spreading In The Early 1960s?, A. Charles Darwin And James Hutton, B. Harry Hess And R

Who were the two scientists who proposed the theory of seafloor spreading in the early 1960s? a. Charles Darwin and James Hutton b. Harry Hess and Robert Dietz c. John Butler and Arthur Smite d. f. Vine and d. Mathews   Answer: The correct answer is letter b. Harry Hess and Robert Dietz. Explanation: The two two scientists who proposed the theory of seafloor spreading in the early 1960s are Harry Hess and Robert Dietz. Harry Hess found out how oceanic mountain ranges, called oceanic ridges are essential to the tectonic movement that results in the drift of continents. Seafloor Spreading is the process that occurs at mid-ocean ridges wherein new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. According to this theory, the ocean floor is about a few hundred million years old, making it significantly younger than the continent. This supports the idea that molten rocks takes a long time to come out of volcanic-ally active oc...

A Function F Is Given By F(4x-1) = 4x2+5. Evaluate F(15).

A function f is given by f(4x-1) = 4x2+5. Evaluate f(15).   Answer:905 would be the answer if the function were defined as f(x) = 4x^2+5: Step-by-step explanation: But the function is defined as f(4x-1) = 4x^2+5. To evaluate f(15), you need to determine the value of x that makes 4x-1 equal to 15. 4x-1 = 15 4x = 16 x = 4 THAT is the value you need to substitute into the expression 4x^2+5 to get the answer.
