Staci works at an apple orchard during the fall. On average, 70% of the apples sold are green and 30% are red. Use the following random number table to predict the probability that the next three apples sold will be green. Let the digits 0-6 represent a green apple and the digits 7-9 represent a red apple. a. Based on your experiment, what is the probability that the next 3 apples sold will be green? Random numbers 91037 84668 56950 17392 b. How many trials did you perform? What will most likely happen if you perform more trials?

This website can show you the table

I apologize but I'm not sure as to what the answer is and I don't want to mislead you with potential false information... @jabez177 might be able to help you though

The probability of an apple being green is like flipping a coin. But rather than 50/50 we have 70/30 with 70% chance of it being green and 30% it being red. We assume independence from one apple draw to the next. So probability of three greens in a row is just $$ 0.7\times 0.7\times 0.7 $$ Does this make sense?

OpenStudy (anonymous):

Yeah, but can you elaborate a little more for more clarity please?

OpenStudy (ybarrap):

Using the random data we have, assuming 0-6 = green and 7-9 = red The ratio of green to total is 91037 rgggr = 3/5 84668 rgggr = 3/5 56950 ggrgg = 4/5 17392 grgrg = 3/5 So the probability of green from experiment is about $$ \cfrac{3+3+4+3}{5+5+5+5}=\cfrac{13}{20}=0.65 $$ This is pretty close to 0.7. As you do more experiments, we'd expect a number closer to 0.70. Does this make sense?

Thank you SSSOOOOOO much!!
