Question

if a conservation effort has a 40% chance of success, what is the probability it will fail? a. 60% b. 40% c. 20% d. 80%

Explanation:

Step1: Use probability formula

The sum of probabilities of all possible outcomes is \(100\%\). Let \(P(\text{success}) = 40\%\) and \(P(\text{fail})\) be the probability of failure. Then \(P(\text{success})+P(\text{fail}) = 100\%\).

Step2: Solve for \(P(\text{fail})\)

\(P(\text{fail})=100\% - P(\text{success})\). Substitute \(P(\text{success}) = 40\%\) into the formula: \(P(\text{fail})=100\% - 40\%=60\%\)

Answer:

A. 60%
