Question

In a survey, 20% of male college students said they lied to get a woman to go out on a date with them. If a male college student is chosen at random, find the probability that he does not lie to get a date with a woman. Express the answer as a fraction, percent, or decimal number rounded to 2 decimal places.

Answer 1

Given that in a survey 20% of male college students said they lied to get a woman to go out on a date with them.

Therefore the probability that male college students said they lied to get a woman to go out on a date with them is p=0.20

Hence, the probability that male college students said they does not lie to get a date with woman is q=1-p

q=1-0.20

q=0.80

Therefore if a male college student is chosen at random, the probability that he does not lie to get a date with a woman is 0.80
