We have a total of 72+81+5=158 males and 103+68+7=178 females surveyed. That's a total n = 158 + 178 = 336.
Assuming this is a representative population, we have 72 males in favor which we combine with the 178 females for a total 72+178=250 people that are female or in favor. So our probability is

Answer:
8/125
Step-by-step explanation:

red balls : 6
yellow balls : 7
green balls : 2

P(red ball) = 6 / 15 = 2/5
P(3 consecutive red balls with replacement),
= (2/5) x (2/5) x (2/5)
= 8/125
