Webb7 juli 2024 · A continuous distribution’s probability function takes the form of a continuous curve, and its random variable takes on an uncountably infinite number of possible values. This means the set of possible values is written as an interval, such as negative infinity to positive infinity, zero to infinity, or an interval like [0, 10], which represents all real … WebbTo find the probability of 2 correct answers, just add these three probabilities together. You get P(2 correct answers ) = P(RRW) + P(RWR) + P(WRR) = (1 4)2(3 4)1 + (1 4)2(3 4)1 + (1 4)2(3 4)1 = 3(1 4)2(3 4)1 d. You could go through the same argument that you did above and come up with the following: Hopefully you see the pattern that results.
