Question
If P(A) = 0.46, P(B) = 0.5, and A and B are mutually exclusive, Find P(A or B). 0 0.96 0.48 0.04 A poll was taken of 14, 499 working adults aged 40-70 to determine their level of education. The participants were classified by sex and by level of education. The results were as follows. A Person is selected at random. Compute the probability that the person is female and has a bachelors degree. 0.257 0.256 0.528 0.998 If a single card is drawn from an ordinary deck of cards, what is the probability of drawing a jack, queen, king, or ace? 4/13 17/52 9/26 5/13Explanation / Answer
1) if A and B are mutually exclusive P(A or B)=P(A)+P(B)=0.5+0.46=0.96
2)number of people female and having bachelor's degree=3714
hence probability =3714/14499=0.256
3)total number of jack, queen,king or ace =16
hence probability =16/52=4/13
