Question

7. A discrete random variable x can assume five possible values: 2, 3, 5, 8, 10. Its probability distribution is shown here: x | p(x) 2 | 0.10 3 | 0.15 5 | ? 8 | 0.20 10 | 0.30 (a) What is P(X = 5)? (1pt) (b) What is the probability that x equals to 2 and 10?(1pt) (c) What is P(x ? 5)?(2pt)

Step 1

The distribution shows the probabilities of each possible value of X. We need to answer three questions based on this distribution: * **(a)** Find the probability of X being equal to 5, i.e., $P(X = 5)$. * **(b)** Find the probability of X being equal to 2 or Show more…
