Now we can answer questions like what are the chances of drawing 2 blue marbles answer.
Theoretical probability of drawing 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.
And got 1 10 as a result.
In some experiments the sample space may change for the different events.
What is probability without replacement or dependent probability.
There are 5 red marbles 8 blue marbles and 12 green marbles in a bag.
What is the theoretical probability of landing on a 7.
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.
So 50 out of 100 when this is the same thing as a 1 2 probability.
We can also find the theoretical probability of an event.
Well theoretically there s 100 equally likely possibilities there s 100 marbles in the bag.
And 50 of them involve picking a magenta.
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.
So you could say well theoretically there is a 1 2 probability i just did the math.
Did you see how we multiplied the chances.
The table shows the results.
Therefore the number of favorable outcomes 8.
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.
A marble is drawn its color is recorded and then the marble is placed back in the bag.
For which marble is the experimental probability of drawing the marble the same as the theoretical probability.
This process is repeated until 30 marbles have been drawn.
What is the theoretical probability of randomly drawing a red 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.
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.
It is a 2 5 chance followed by a 1 4 chance.
A bag contains 10 red marbles 8 blue marbles and 2 yellow marbles.
There are 8 blue marbles.
