The total number of marbles in the bowl is 140.The number of black marbles is 80 and the number of green marbles is 28. Therefore, the number of blue marbles is:140 - 80 - 28 = 32The probability of pulling a red marble out of the bowl is:Number of red marbles / Total number of marbles= 0 / 140= 0Therefore, the probability of Christine pulling a red marble out of the bowl is 0.
So, the probability of Christine pulling a blue marble out of the bowl is:Number of blue marbles / Total number of marbles= 32/140= 0.2286 or 22.86%Therefore, the probability of Christine pulling a blue marble out of the bowl is 22.86%.
Theoretical P(blue) =
Remember to round your answer to the nearest hundredth.
Experimental P(blue) =
Remember to round your answer to the nearest hundredth.
Theoretical P(blue) = Number of blue marbles / Total number of marbles = 32 / 140 ≈ 0.23
Experimental P(blue) = Number of blue marbles pulled out / Total number of marbles pulled out
This cannot be determined without knowing how many marbles Christine has actually pulled out of the bowl.
Experimental P(blue)
To calculate the experimental probability of Christine pulling a blue marble out of the bowl, we need to know how many marbles she has actually pulled out and how many of them were blue.
Let's say Christine pulled out 20 marbles and 5 of them were blue.
Experimental P(blue) = Number of blue marbles pulled out / Total number of marbles pulled out = 5 / 20 = 0.25
Therefore, the experimental probability of Christine pulling a blue marble out of the bowl is 0.25 or 25%.
