Answer:
A) 99.5%
B) 42.1%
Step-by-step explanation:
A) Since the probability of 3 sixes is 0.5%, the probability of less than 3 sixes (that is, zero, one, or two sixes) is 100% - 0.5%, or 99.5%
B ) Since the probability of no sixes is 57.9%, the probability of at least 1 six is 100% - 57.9%, or 42.1%
Answer: C
You have to multiply the x by 75 to get the y value
1 x 75 = 75
2 x 75 = 150
3 x 75 = 225
And so on...

x=15
165+x=180
x=180-165
D
This is the only reasonable answer
