Step 7 (d) Compute u, the expected value of the number of fish caught per fisherman in a 6-hour period. Recall that the expected value is calculated using the formula u = xP(x), where x is the value of a random variable, P(x) is the probability of that variable, and the sum is taken for all values of the random variable. First determine xP(x), the product of x and P(x), for each value of x (let x = 4 for the value of "4 or more"). 1 3 4 or more P(x) 0.46 0.33 0.17 0.03 0.01 1(0.33) 0(0.46) ХP(x) = 0 Submit Skip (you cannot come back).
