Answer:
Probablity that the person will get both things checked = 0.035
Step-by-step explanation:
The statement given in the end is not correct considering the first two statements as valid.
Statement 1
Probability that a person stopping at a petrol pump will get his tyres checked is 0.12
Statement 2
Probability that a person stopping at a petrol pump will get his tyres checked is 0.29
Statement 3
Probability that a person stopping at a petrol pump will get his tyres and oil checked is 0.07 (incorrect)
Probability that the person will get both things checked = 0.12 x 0.29 = 0.035
