19/25
6/19
19/6
6/25

Answer 1

The survey sampled 38 people that said yes and 12 that said no so you find that answer by adding all the people that said yes with all the people that said no. 38+12 = 50

38 people out of 50 enjoyed the concert, so that gives you the probability that 38/50 enjoyed it. We take that to its lowest possible number by dividing the top and bottom numbers by 2 resulting in (38/2)/(50/2)=19/25

Answer 2

38+12= 50 people in concert

38/50=19/25 enjoyed concert

Answer 3

38+12=50
.
.p=38/50=19/25
