Answer:
2/5
Step-by-step 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
