Answer:
n≅376
So sample size is 376.
Step-by-step explanation:
The formula we are going to use is:

where:
n is the sample size
p is the probability of favor
q is the probability of not in favor
E is the Margin of error
z is the distribution
α=1-0.98=0.02
α/2=0.01
From cumulative standard Normal Distribution

p is taken 0.5 for least biased estimate, q=1-p=0.5

n≅376
So sample size is 376
Answer:
x≤9
Step-by-step explanation:
x ≤6+3

Total outcomes in which Billy can get 5 or more : 2 <u>outcomes</u>
Total outcomes = 6
So, the probability of getting 5 or higher is ~



Therefore, the correct choice is C
