Casey finds that when asked for their email address, 1/5 of her customers will share their address with her. To simulate the beh
avior 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.

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:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
