Zorluk: OrtaExperimental and Theoretical Probability

In a probability experiment, a card is drawn at random with replacement from a bag containing red, green, and blue cards. After conducting 250250 trials, a green card was drawn 8585 times. Given that the theoretical probability of drawing a green card is 0.300.30, calculate the positive difference between the experimental probability and the theoretical probability of drawing a green card.

Cevap: 0.04

Cevap

The positive difference between the experimental probability and the theoretical probability is 0.04.
The experimental probability is calculated as the ratio of observed favorable outcomes to total trials: \(\frac{85}{250} = 0.34\). Subtracting the given theoretical probability of \(0.30\) yields a positive difference of \(|0.34 - 0.30| = 0.04\).

Adım Adım Çözüm

1
Determine experimental probability from trial data
Experimental probability = 85 / 250 = 0.34
Experimental probability is calculated as the ratio of observed favorable trials to the total number of trials executed.
2
Subtract theoretical probability from experimental probability
|0.34 - 0.30| = 0.04
Finding the positive difference requires subtracting the theoretical probability (0.30) from the experimental relative frequency (0.34).

Anahtar Kavram

Experimental probability is determined empirically by dividing the number of times an event occurs by the total number of trials, whereas theoretical probability is based on expected outcomes under ideal conditions.
