Question

PLZ HELP I WILL GIVE BRANILYITS ANSWER IF RIGHT

Sandy is helping her uncle at this coffee shop. She observes that, when ordering coffee, 13 of customers select chocolate flavoring.

To simulate the behavior of the next 5 customers, she lets the number 1 represent someone ordering chocolate, and she lets the numbers 2 or 3 represent someone ordering a different flavor. She writes the numbers 1, 2, and 3 on cards and mixes them up.

Sandy then picks one card, records the result, and puts the card back. She does this process four more times to represent 5 customers and to complete 1 trial of the experiment.


She repeats this experiment for a total of 10 trials. The results are recorded in the table.

12323 13123 22222 23111 11322 31112 23331 11231 32332 13111
Using this simulation, what is the probability that 3 or more of the next 5 customers will order chocolate?

Explanation:

Sandy is helping her uncle at this coffee shop. She observes that, when ordering coffee, 13 of customers select chocolate flavoring.

To simulate the behavior of the next 5 customers, she lets the number 1 represent someone ordering chocolate, and she lets the numbers 2 or 3 represent someone ordering a different flavor. She writes the numbers 1, 2, and 3 on cards and mixes them up.

Sandy then picks one card, records the result, and puts the card back. She does this process four more times to represent 5 customers and to complete 1 trial of the experiment.

She repeats this experiment for a total of 10 trials. The results are recorded in the table.

12323 13123 22222 23111 11322 31112 23331 11231 32332 13111

We are asked the probability that 3 or more of the next 5 customers will order chocolate.

the trials such that 3 or more customers order chocolate flavor are:

23111 31112 11231 13111

so, the probability is no. of favorable outcomes/total no. of outcomes

= 4/10

= 2/5
