4,915 people were surveyed about their recent purchases. 1,027 of those people surveyed bought a lawn mower within the last year, 918 bought a snow blower within the last year, and 3,387 didn’t buy either of the two.
a) How many people bought a lawn mower and a snow blower?
b) How many people bought at least one of the two?
To find the number of people who bought both a lawn mower and a snow blower (a), we need to subtract the number of people who bought neither from the total number of people who were surveyed.
a) Number of people who bought both = Total number surveyed - Number of people who bought neither
Number of people who bought both = 4,915 - 3,387
Number of people who bought both = 1,528
So, 1,528 people bought both a lawn mower and a snow blower.
To find the number of people who bought at least one of the two (b), we can add the number of people who bought a lawn mower and the number of people who bought a snow blower, and then subtract the number of people who bought both.
b) Number of people who bought at least one of the two = Number of people who bought a lawn mower + Number of people who bought a snow blower - Number of people who bought both
Number of people who bought at least one of the two = 1,027 + 918 - 1,528
Number of people who bought at least one of the two = 1,417
So, 1,417 people bought at least one of the two (a lawn mower or a snow blower).
