You and your friend decide to get your cars inspected. You are informed that 73% of cars pass inspection. If the event of your car's passing is independent of your friend's car, a) What is the probability that your car passes inspection?

73% probability that your car passes inspection.

Step-by-step explanation:

For each car, there is a 73% probability of passing inspections.

The probability of a car passing inspection is independent from other cars.

What is the probability that your car passes inspection?

Since the probabilities are independent for each car, there is a 73% probability that your car passes inspection.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
