A consumer organization estimates that over a 1 -year period $15 \%$ of cars will need to be repaired only once, $7 \%$ will need repairs exactly twice, and $1 \%$ will require three or more repairs. What is the probability that a car chosen at random will need a) no repairs? b) no more than one repair? c) some repairs?
A consumer organization estimates that over a 1-year period 17% of cars will need to be repaired only once, 7% will need repairs exactly twice, and 4% will require three or more repairs. Suppose someone wanted to find certain probabilities regarding the number of repairs needed for the two cars they own. They use the Multiplication Rule to calculate these probabilities. Complete parts a) and b) below.
