Answer:
=IF(E10>=4,"Y","N")
Step-by-step explanation:
This was already correctly answered. I'll add some futher explanation.
The "E10>=4" states "The contents of cell E10 are greater than, or equal to, 4. The entry after the comma is the response if the statement is TRUE. The reponse may be a numerical vale, such as 1, a calculation, or taex. Text must be bounded by the quotation marks: "Y". The entry after the last comma is the response if the statement were FALSE. Here, is will return an N.
