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

<h3>Probability</h3>
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.
There are 17 are the favorable no. of outcomes and 20 are the total outcomes.
The probability that, out of the next 4 customers, fewer than 2 will share their email address is;
Hence, the probability that, out of the next 4 customers, fewer than 2 will share their email address is 17/20.
