In a newspaper poll concerning violence on television, 600 people were asked, "What is your opinion of the amount of violence on prime-time television--is there too much violence on television?"

Question

Use the data in the table below to find the given probabilities.

	Yes	No	Don't Know	Total
Men	162	95	23	280
Women	256	45	19	320
Total	418	140	42	600

(a) p(W | N) = and what percent

(b) p(N ∩ W) = and what percent

(c) p(W ∩ N) = and what percent

Answer 1

a) 45/140=9/28= about 32.14%

b) 45/600= 9/120 = 3/40=7.5/100 = 7.5%

c) = same as b) 7.5%

if N means No, and W=Women

and a) is a conditional probability

while b) and c) are intersections,joint probabilities
