Question:
The probability of a certain brand of battery going dead within 15 hours is 1/3. Noah has a toy that requires 4 of these batteries. He wants to estimate the probability that at least one battery will die before 15 hours are up.1.Noah will simulate the situation by putting marbles in a bag. Drawing one marble from the bag will represent the outcome of one of the batteries in the toy after 15 hours. Red marbles represent a battery that dies before 15 hours are up, and green marbles represent a battery that lasts longer.How many marbles of each color should he put in the bag? Explain your reasoning.
Answer:
The number of marbles of each color that should be present in the bag is;
1 red marble and 2 green marbles
Step-by-step explanation:
Here, we note that the probability of a battery going dead = 1/3 and the
Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag
That is there should be 1 red marble and 2 green marble in the bag.

The Pythagorean theorem is a formula to solve for hypotenuse the formula is a squared plus b squared equals c squared. The Pythagorean theorem was made by someone for math which is four triangles that A in the equation is for the side of the right triangle B is for the other side and C is the hypotenuse. the photographer in theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse. It is a fundamental relationship between the three sides of a right triangle; you must use two sides in order to find the hypotenuse. many ways to make a formula for the Pythagorean theorem but the most popular one is a squared plus b squared equals c squared. there's a book and it's called the Pythagorean proposition it contains over 300 formulas for the Pythagorean theorem. a man who went by Pythagoras had found the Pythagorean theorem in the school of mathematics and Cortana he was a Greek Seaport in southern Italy he was going to get too many contributions to mathematics although some of them may have actually been the work of his students that he had taught. Pythagorean theorem is the most famous mathematical contribution in history. It was created in 1900 BC. the reason why it was created that the Egyptians wanted a perfect 90° angle to build the pyramids which were actually two right triangles whose hypotenuse form the edges of the pyramid. there is a rumor that the Chinese had also developed the Pythagoras Theorem using the areas of the sides long before Pythagoras himself.

Answer:
Tristan has a 17/24 lb fraction of a pound of grapes now.
Step-by-step explanation:
Given
- The number of grapes Tristan had at home = 1/3 lb
- The number of grapes Tristan had at the store = 3/8 lb
To determine
What fraction of a pound of grapes does Tristan have now?
In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.
i.e.
Current number grapes = 1/3 + 3/8
Least Common Multiple of 3, 8: 24
Adjust fractions based on L.C.M
= 8/24 + 9/24
Apply the fraction rule: 
= (8 + 9) / 24
= 17/24 lb
Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.
