Answer:
The parents who didn't answer with either naughty and nice are <u>6</u>.
Step-by-step explanation:
Given:
150 parents were surveyed. 26% said that the kids were naughty and 70% said their kids were nice.
Now, to find parents who didn't answer with either naughty and nice.
<em>So, as given in question:</em>
<em>70% said that their kids are naughty.</em>
<em>26% said that their kids are nice.</em>
So, to get the percentage of parents who didn't answer we subtract.
<em>Thus, the percentage of parents who didn't answer with either naughty and nice:</em>
100% - (70% + 26%)
100% - 96% = 4%.
Hence, 4% of parents didn't answer.
Now, to get how many parents didn't answer we calculate the percentage of the total who didn't answer:
<em>Total parents surveyed = 150.</em>
<em>Parents who didn't answer = 4% of the total parents surveyed.</em>
Therefore, the parents who didn't answer with either naughty and nice are 6.
Notice that the box has a total os 4 + 5 + 3 = 12 balls, since there are 4 that are yellow, then, the probability to randomly obtaining a yellow ball in a single draw is:
therefore, the probability is 0.33 = 33%
