Theoretical Probability Of Drawing Marbles

So you could say well theoretically there is a 1 2 probability i just did the math.

Theoretical probability of drawing marbles.

The chances of drawing 2 blue marbles is 1 10. Therefore the number of favorable outcomes 8. Three sides of the cube are shown. The table shows the results.

A 25 b 20 c 62 5 d 41 7 25 points. This process is repeated until 30 marbles have been drawn. It is a 2 5 chance followed by a 1 4 chance. And so this is sometimes the event in question right over here is picking the yellow marble.

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

There are 8 blue marbles. A bag contains 5 marbles that are each a different color. 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. In some experiments the sample space may change for the different events.

And 50 of them involve picking a magenta. The probability of picking a yellow 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. So 50 out of 100 when this is the same thing as a 1 2 probability.

A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles. And got 1 10 as a result. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag. What is probability without replacement or dependent probability.

What is the theoretical probability of landing on a 7. The sample space for the second event is then 19 marbles instead of 20 marbles. So they say the probability i ll just say p for probability. There are 5 red marbles 8 blue marbles and 12 green marbles in a bag.

Did you see how we multiplied the chances. A marble is drawn its color is recorded and then the marble is placed back in the bag.
