Sheila drew single marbles from a bag, recorded the outcome, and replaced the marble. In 50 draws, Sheila drew 20 white marbles and 30 black marbles. What is the experimental probability that the next marble will be black?
With this limited data, best estimate = 30/50 = ?
To find the experimental probability of drawing a black marble, you need to divide the number of successful outcomes (in this case, black marbles) by the total number of trials (the total number of draws Sheila made).
In this case, Sheila made 50 draws, with 30 of them being black marbles. So, the experimental probability of drawing a black marble can be calculated as:
Experimental probability = Number of successful outcomes / Total number of trials
Experimental probability = 30 / 50
Simplifying this fraction, we get:
Experimental probability = 3/5
Therefore, the experimental probability that the next marble Sheila draws will be black is 3/5 or 0.6 (60%).
