Answer:
31/20
Step-by-step explanation:
You need to plug in x as y-3.
so instead of 10x+10y=1 it is 10(y-3)+10y=1
Then just simplify the equation to find the value of y
Total number of people in the sample = 193 + 127 + 96 = 416
Probability of picking 23-30 year old = 92 /416 = 0.2212 ( not including the people who smoke)
Number of people who smoke = 60+35+23 = 118 people
Prob(someone who smokes) = 118/416 = 0.2837
So required probability = 0.2837 + 0.2212 = 0.505 (answer)
Answer:
