Theoretical Probability Of Drawing Marbles

A marble is drawn its color is recorded and then the marble is placed back in the bag.

Theoretical probability of drawing marbles.

So you could say well theoretically there is a 1 2 probability i just did the math. The sample space for the second event is then 19 marbles instead of 20 marbles. There are 8 blue marbles. Three sides of the cube are shown.

Did you see how we multiplied the chances. There are 5 red marbles 8 blue marbles and 12 green marbles in a bag. Find the theoretical probability of getting a blue marble. What is the theoretical probability of randomly drawing a red marble.

What is probability without replacement or dependent probability. Now we can answer questions like what are the chances of drawing 2 blue marbles answer. The table shows the results. So they say the probability i ll just say p for probability.

The chances of drawing 2 blue marbles is 1 10. A 25 b 20 c 62 5 d 41 7 25 points. It is a 2 5 chance followed by a 1 4 chance. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag.

And 50 of them involve picking a magenta. 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. In some experiments the sample space may change for the different events. What is the theoretical probability of landing on a 7.

We can also find the theoretical probability of an event. This process is repeated until 30 marbles have been drawn. And so this is sometimes the event in question right over here is picking the yellow marble. A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles.

Therefore the number of favorable outcomes 8. 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. A bag contains 5 marbles that are each a different color. The probability of picking a yellow marble.

So 50 out of 100 when this is the same thing as a 1 2 probability. For which marble is the experimental probability of drawing the marble the same as the theoretical probability.
