Theoretical Probability Of Drawing Marbles

For which marble is the experimental probability of drawing the marble the same as the theoretical probability.

Theoretical probability of drawing marbles.

What is probability without replacement or dependent probability. Pleasee help anyone given the bag of marbles above find the probability of first drawing a green marble and then drawing a blue marble without replacing the first marble. What is the theoretical probability of randomly drawing a red marble. For example a marble may be taken from a bag with 20 marbles and then a second marble is taken without replacing the first marble.

This process is repeated until 30 marbles have been drawn. Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles. The table shows the results. The chances of drawing 2 blue marbles is 1 10.

Find the theoretical probability of getting a blue marble. The sample space for the second event is then 19 marbles instead of 20 marbles. A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles. Three sides of the cube are shown.

There are 5 red marbles 8 blue marbles and 12 green marbles in a bag. Therefore the number of favorable outcomes 8. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag. So 50 out of 100 when this is the same thing as a 1 2 probability.

In some experiments the sample space may change for the different events. There are 8 blue marbles. The probability of picking a yellow marble. Did you see how we multiplied the chances.

We can also find the theoretical probability of an event. A bag contains 5 marbles that are each a different color. So they say the probability i ll just say p for probability. What is the theoretical probability of landing on a 7.

A marble is drawn its color is recorded and then the marble is placed back in the bag. So you could say well theoretically there is a 1 2 probability i just did the math. And so this is sometimes the event in question right over here is picking the yellow marble. The possible outcomes of rolling a number cube are landing on a 1 landing on a 2 landing on a 3 landing on a 4 landing on a 5 or landing on a 6.

And 50 of them involve picking a magenta. And got 1 10 as a result.
