Andrej [43]

Complete question :

Suppose that of the 300 seniors who graduated from Schwarzchild High School last spring, some have jobs, some are attending college, and some are doing both. The following Venn diagram shows the number of graduates in each category. What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as a decimal precise to two decimal places.

What is the probability that a randomly selected graduate attends college if he or she has a job? Give your answer as a decimal precise to two decimal places.

Answer:

0.56 ; 0.60

Step-by-step explanation:

From The attached Venn diagram :

C = attend college ; J = has a job

P(C) = (35+45)/300 = 80/300 = 8/30

P(J) = (30+45)/300 = 75/300 = 0.25

P(C n J) = 45 /300 = 0.15

1.)

P(J | C) = P(C n J) / P(C)

P(J | C) = 0.15 / (8/30)

P(J | C) = 0.5625 = 0.56

2.)

P(C | J) = P(C n J) / P(J)

P(C | J) = 0.15 / (0.25)

P(C | J) = 0.6 = 0.60

larisa86 [58]

Answer:

a)  2/2 + 2/2 = 2

b)  2/2 + 1/2  = 3/2

c)  2/2 + 0/2  = 1

d)  0/2 + 0/2 = 0

Step-by-step explanation:

a) 2 points :  2/2 + 2/2 = 2    

            if henry wins both games than we get  probability =2

b) 1  1/2 or 3/2 :  2/2 + 1/2 = 3/2

             if henry wins one game and tie another game  we get probability =3/2

c) 1 point:  2/2 + 0/2 = 1

              if henry wins one game and loose second game, we get                                                       probability 1

d) 0 points: 0/2 + 0/2 = 0

                 if henry loose both games we get probability 0
