Answer:
B, and D
Step-by-step explanation:
1. We are given the data set: S, E, M, I, T, R, O, P, I, C, A, L
Then we are told to find the probability of slelecting a vowel from the pile. There are 5 vowels in the data set, so the probability of drawing one on the first try is
2. A standard number cube has the following numbers: 1, 2, 3, 4, 5, 6, so the probability of recieving a 0 wouldn't be possible as there isn't a zero on a standard number cube.
Hope this Helps!

Answer:
a) Let her comic books be x
b) as she sold half it will be
+ 8 = 13 ( as she sold half and then she bought 8 more that means plus and then now she have 13 that means = 13)
c ) to solve to find the books she have we need to
+ 8 = 13
Transpose
= 13 - 8
= 5
x = 5 × 2
x = 10
the comic books were 10
we can even cross- check to see if the value is right instead of x put 10
+ 8 = 13
5 +8 = 13
13 = 13
Cross-checked
