Theoretical Probability Of Drawing Marbles

Did you see how we multiplied the chances.

Theoretical probability of drawing marbles.

Therefore the number of favorable outcomes 8. What is the theoretical probability of landing on a 7. Find the theoretical probability of getting a blue marble. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag.

This process is repeated until 30 marbles have been drawn. 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. In some experiments the sample space may change for the different events. A bag contains 5 marbles that are each a different color.

Three sides of the cube are shown. There are 5 red marbles 8 blue marbles and 12 green marbles in a bag. And 50 of them involve picking a magenta. The probability of picking a yellow marble.

So they say the probability i ll just say p for probability. A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles. What is probability without replacement or dependent probability. Now we can answer questions like what are the chances of drawing 2 blue marbles answer.

We can also find the theoretical probability of an event. The sample space for the second event is then 19 marbles instead of 20 marbles. The table shows the results. A 25 b 20 c 62 5 d 41 7 25 points.

The chances of drawing 2 blue marbles is 1 10. It is a 2 5 chance followed by a 1 4 chance. There are 8 blue marbles. So 50 out of 100 when this is the same thing as a 1 2 probability.

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 so this is sometimes the event in question right over here is picking the yellow marble. And got 1 10 as a result. What is the theoretical probability of randomly drawing a red marble.

For which marble is the experimental probability of drawing the marble the same as the theoretical probability. So you could say well theoretically there is a 1 2 probability i just did the math.
