An experiment consists of four outcomes with P(E₁)= 0.2,P(E₂)= 0.3,and P(E₃)= 0.4.The probability of outcome E₄ is A)0.500 B)0.024 C)0.100 D)0.900

Question

Quizplus · Accepted Answer

The total probability of all outcomes in an experiment must equal 1. Given the probabilities of the first three outcomes are 0.2, 0.3, and 0.4, their sum is 0.9. Therefore, the probability of the fourth outcome must be 1 - 0.9 = 0.1 to ensure the total probability equals 1.
