The probability that Color Me Dandy wins a horse race at Batavia Downs given good track conditions is 0.60. The probability of good track conditions on any given day is 0.85. What is the probability that Color Me Dandy wins or the track conditions are good

Probability can't be found because of inadequate data

Step-by-step explanation:

Since we have the rules to be

Multiplication rule

P(A and B) = P(AnB) = P(A)×P(B) or P(A)×P(B|A) or P(B)×P(A|B)

Addition rule

P(A or B) = P(A)+P(B)-P(AnB)

We have that

P(Color Me Dandy wins|Good track conditions) = 0.06

P(Good track conditions) = 0.85

Now to find probability that Color Me Dandy wins or the track conditions are good, we weren't give the probability of colour me Dandy wins only. So, the information is adequate to find the probability of color me Dandy wins.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
