If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
A) (1-.12)(1-.29) = ?
B) It is in your data, .07.
The probability that a person stopping at petrol pump will get his tyres checked is 0.12, the probability that he will get his oil checked is 0.29 and the probability that he will get both checked is 0.07.

(A)0.34
(B)0.24
(B)0.24
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
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

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
