In a random sample of male and female graduates of the New Y
In a random sample of male and female graduates of the New York School for the Arts between the ages of 22-35 you know that:
• the probability a man is a ballet dancer is 0.245.
• the probability a woman is a musical performer is 0.365
• the probability a man is a musical performer, given that he\'s a ballet dancer is 0.250.
• the probability a woman is an actress is 0.550.
• the probability a woman is an actress, given that she\'s a musical performer is .785.
Compute the following probabilities:
A. P (man is a ballet dancer and a musical performer)
B. P (woman is an actress and a musical performer)
C. P (woman is an actress or a musical performer)
Solution
=0.245*(1-0.365)=0.155
b. P (woman is an actress and a musical performer)
=0.365*0.55=0.2
c. P (woman is an actress or a musical performer)
=P(woman is an actress)+P(musical performer)-P(actress or performer)
=0.55+0.365-0.785*0.365=0.628
