In a survey it was found that 21 persons it was found that 21 persons liked product a, 26 liked product b, and 29 liked product c. if 14 people liked product a and b, 12 people liked products c and a, 14 people liked products b and c and 8 liked all the three products. find,
i) the number of people who liked at least one product.
ii) the number of people who like product c only.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
