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: Option 'B' and 'C' are correct.
Step-by-step explanation:
Since we know that irrational numbers are those real number which cannot be written in form.
Rational numbers are those real numbers which can be written in form.
Inverse property of multiplication is that property in which we write a number in reciprocal form .
Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.
Hence, belongs to rational numbers sets and inverse property of multiplication sets.
Therefore, Option 'B' and 'C' are correct.
