(A) The total number of past working days is $200$.Let $E$ be the event that tomorrow's output will have not more than $5$ defective parts.'Not more than $5$' means the number of defective parts can be $0, 1, 2, 3, 4,$ or $5$.From the given table,the number of days corresponding to these values are:Days with $0$ parts: $50$Days with $1$ part: $32$Days with $2$ parts: $22$Days with $3$ parts: $18$Days with $4$ parts: $12$Days with $5$ parts: $12$Total number of favorable outcomes $= 50 + 32 + 22 + 18 + 12 + 12 = 146$.The probability $P(E)$ is given by:$P(E) = \frac{	ext{Number of favorable outcomes}}{	ext{Total number of trials}}$$P(E) = \frac{146}{200} = 0.73$.

Outcome	$1$	$2$	$3$	$4$	$5$	$6$
Frequency	$180$	$150$	$160$	$170$	$150$	$190$
