Need help, please show work

Red snapper is a rare and expensive reef fish served at upscale restaurants. A certain law prohibitsestaurants from serving a cheaper, look-alike variety of fish (vermilion snapper or lane snapper) to customers who order red snapper. Researchers at a university used DNA analysis to examine fish specimens labeled "red snapper" that were purchased form vendors across the country. The DNA tests revealed that 75% of the specimens were not red snapper, but the cheaper, look-alike variety of fish. a. Assuming that the results of the DNA analysis are valid, what is the probability that you are actually served red snapper the next time you order it at a restaurant? The probability is Round to the nearest hundredth as needed)

Explanation / Answer

Answer to the question is as follows:

P( cheaper look alike is served instead of the actual red snapper) = .75

a. Now, if we assume DNA analysis results are valid, P( actual red snapper was served instead of a cheaper look alike)

= 1- P( cheaper look alike is served instead of the actual red snapper)

= 1-.75

= .25

There is a 25% chance that the original red snapper and not its duplicate is served
