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
simulate the situation to estimate the probability that at least one battery
will die before 15 hours are up.
b.
After doing the simulation 5 times, Noah has the following results.

What should he use as an estimate of the probability that at least
one battery will die within 15 hours? (Write your answer as a
fraction, decimal, or percent.)

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
