Three teams of scientists are working to find a vaccine for a particular virus. The probability the first team will succeed before the end of the year is 0.1. The probability the second team will succeed before the end of the year is 0.2, and the probability the third team will succeed before the end of the year is 0.25. Assume these are independent events.

Find the probability there will be a vaccine before the end of the year, that is,find the probability that at least one of the teams succeeds before the end of the year.

Give the probability as a decimal.If rounding, give to 4 decimal places.

The probability is
