Answer:
18 is .20
19 is c+5 over 3
Step-by-step explanation:
18.
p= 4C 1 /4C1 * 5C1 = 4 / 4*5 = .20
19.
(3a - 5) / c = 1
3a - 5 = c
3a = c + 5
a = (c + 5) / 3
#18 is B because 4/20 possibilities add up to ten.
#19 is C because the bs cancel out and you get 3a-5=c -> 3a=c+5 -> a= (c+5)/3
#19 is C because the bs cancel out and you get 3a-5=c -> 3a=c+5 -> a= (c+5)/3
