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.

For which marble is the experimental probability of drawing the marble the same as the theoretical probability. A bag contains 5 marbles that are each a different color. What is the theoretical probability of randomly drawing a red marble. Find the theoretical probability of getting a blue marble.

This process is repeated until 30 marbles have been drawn. Now we can answer questions like what are the chances of drawing 2 blue marbles answer. In some experiments the sample space may change for the different events. 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.

A marble is drawn its color is recorded and then the marble is placed back in the bag. The sample space for the second event is then 19 marbles instead of 20 marbles. And got 1 10 as a result. What is probability without replacement or dependent probability.

There are 5 red marbles 8 blue marbles and 12 green marbles in a bag. And so this is sometimes the event in question right over here is picking the yellow marble. Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag. Three sides of the cube are shown.

The table shows the results. What is the theoretical probability of landing on a 7. Therefore the number of favorable outcomes 8. A 25 b 20 c 62 5 d 41 7 25 points.

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. It is a 2 5 chance followed by a 1 4 chance. There are 8 blue marbles. And 50 of them involve picking a magenta.

Did you see how we multiplied the chances. 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 probability of picking a yellow marble. A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles.

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. So they say the probability i ll just say p for probability.
