Question

Casey finds that when asked for their email address, 1/5 of her customers will share their address with her. To simulate the behavior of the next 4 customers, she writes the numbers 1, 2, 3, 4, and 5 on cards and mixes them up.She then picks 4 cards, records the results, and puts the cards back.. She repeats this experiment for a total of 20 trials. The results are shown in the table. Here, she let 1 represent someone sharing an email address and 2, 3, 4, and 5 represent someone not sharing an email address.

4121 1223 4233 3344 2434 4241 5415 3421 5214 2234 4211 1432 5532 4114 4325 4454 4523 4432 3423 1352

Using this simulation, what is the probability that, out of the next 4 customers, fewer than 2 will share their email address? Enter your answer, as a fraction in simplified form, in the box.

Answer 1

Answer: The person who answered forst deserves brainliest.

Someone was not sure if they were correct

Step-by-step explanation:

Answer 2

The probability that, out of the next 4 customers, fewer than 2 will share their email address is 17/20.

What is Probability?

This refers to the mathematical model that shows the likelihood of an event to occur.

Using the given simulation,

There is the selection of cards at random and labelling them 2, 3, 4 and 5

To get the answer,

We would check if 4 random customers are selected, fewer than 2 will share their email address are:

1223  4233  3344  2434  4241  5415  3421  2234  1432  5532  4325  4454  4523  4432  3423  1352

i.e. 17 are the favorable no. of outcomes and 20 are the total outcomes

Hence, the probability is 17/20.
