Theoretical probability of drawing marbles.

So 50 out of 100 when this is the same thing as a 1 2 probability. Now we can answer questions like what are the chances of drawing 2 blue marbles answer. And 50 of them involve picking a magenta. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag.

Three sides of the cube are shown. A bag contains 5 marbles that are each a different color. The chances of drawing 2 blue marbles is 1 10. 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.

And so this is sometimes the event in question right over here is picking the yellow marble. In some experiments the sample space may change for the different events. The probability of picking a yellow marble. So you could say well theoretically there is a 1 2 probability i just did the math.

This process is repeated until 30 marbles have been drawn. So they say the probability i ll just say p for probability. It is a 2 5 chance followed by a 1 4 chance. There are 5 red marbles 8 blue marbles and 12 green marbles in a bag.

For which marble is the experimental probability of drawing the marble the same as the theoretical probability. Find the theoretical probability of getting a blue 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. 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.

The sample space for the second event is then 19 marbles instead of 20 marbles. What is probability without replacement or dependent probability. We can also find the theoretical probability of an event. There are 8 blue marbles.

Therefore the number of favorable outcomes 8. A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles. What is the theoretical probability of landing on a 7. Did you see how we multiplied the chances.

What is the theoretical probability of randomly drawing a red marble. And got 1 10 as a result.
