Aschool conducts a recipe contest in which 1 student gets first place, 1 student gets second place, 1 student gets third place, and 10 students tie for fourth place. fifty students enter the contest. if x represents the distribution of prizes, which graph represents the probability distribution for a randomly selected student?

A graph of the probability distribution is attached.

Step-by-step explanation:

The probability that a student gets first place is 1/50.  The probability that a student gets second place is 1/50.  The probability that a student gets third place is 1/50.  The probability that a student gets fourth pace is 10/50.  This leaves

50-(1+1+1+10) = 50-13 = 37

students that do not place.

the answer is 15% decrease

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
