Answer:
Total no of person = 410+350 = 760
No of person overweight = 196+164 = 360
Probability of choosing a person who is overweight = 760÷360 = 2.111 or 19/9
Step-by-step explanation:
there are 410 salesperson and 350 construction workers so total workers are 760.
Then, it was found that 164 salesperson and 196 construction workers so, total no people overweight is 360.
by applying the formula:
Probability = Total no of outcome
________________
No of possible outcome
we calculate the probability of choosing a person who is over weight
