Bruno digs them up one day and finds that he has between 30 and 50 bones he counts his bones by putting them into piles of 4 bones and finds he has 3 bones left over he counts them by putting them into piles of 7 bones and finds that he only has 1 bone left over how many bones did he have

The probability that at least one has an accident during the coming year is 0.1336

Step-by-step explanation:

The probability that a randomly selected car will be in an accident in the next year in a particular country is 0.0467

P(Accident)=0.0467

P(No accident)=1-P(Accident)=1-0.0467=0.9533

Now we are supposed to find four cars are randomly selected, find the probability that at least one has an accident during the coming year

So, P( Out of 4 at least 1 has accident )=1-P( none of the 4 cars has accident)

P(Out of 4 at least 1 has accident )=1-(0.9533)(0.9533)(0.9533)

P(Out of 4 at least 1 has accident )=0.1336

Hence the probability that at least one has an accident during the coming year is 0.1336
