-21
Step-by-step explanation:
The probability that less than five items will be sold from the items during the week will be 0.67.
<h3>How to calculate probability</h3>
From the complete question, the number of items that were sold in a week was given in a distribution table.
From the table, the probability that there will be less than a total of 5 items sold during that week will be:
= P(3 or 4 items sold) / P(3 or more items sold)
= (0.15 + 0.05) / (0.15 + 0.05 + 0.05 + 0.05)
= 0.20/0.30
= 0.67
In conclusion, the probability is 0.67.
