When flipping a coin three times, what is the probability of landing on tails all two times? A) 1/4
B) 1/2
C) 3/8
D) 5/8

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

so, converting firstly the mixed fractions to improper fractions and then "adding".
