Answer #1

Here we want to find the probability of that we will not lose money if we purchased first envelope.

The price of the envelope = 25 Euros.

Total number of envelopes = 500

Total number of envelopes which contain 25 Euros or more than 25 Euros = 75 + 150 = 225

So the required probability = 225/500 = 450/1000 = 0.45

So final answer is = 0.45
