b because it contains 40% of the possible results from the random list.
0,1,2,3 v 4,5,6,7,8,9
4 integers to 6 integers
40% success vs 60% fail
step-by-step explanation:
6 adults and 9 children went.
a + c = 15
12a + 9c = 153
12(6) + 9(9) = 153
72 + 81 = 153
c(x)= 6x + 3
b. e = 7.5h
hope this , lovely!
