At an amusement park, the probability that a child eats a hot dog and drinks a soda pop is 0.38. The probability that a child eats a hot dog is 0.61, and the probability that a child drinks soda pop is 0.89. What is the probability (rounded to the nearest hundredth) that a child drinks soda pop given that the child has already eaten a hot dog?
 

0.34

0.43

0.62

0.69

Let  H  = the probability of eating a hot dog

Let S  = the probability of drinking a soda

 

So

 

P ( S  l  H )   =     P (S  and H)                .38    

                           ___________     =       ___    =   .62

                               P(H)                          .61
