To find the expected number of successful sales calls per day, we multiply each possible outcome by its corresponding probability and then sum those products.

Expected value = (0 x 0.2) + (1 x 0.3) + (2 x 0.3) + (3 x 0.2) + (4 x 0.0)

Expected value = 0 + 0.3 + 0.6 + 0.6 + 0 = 1.90

Therefore, the expected number of successful sales calls per day is 1.90, which is closest to option C).
