You need to find a common denominator for the equation 1/18+ 5/6
That would be 18. Since 1/18 already has a denominator of 18 there is no need for anything to happen, but as for 5/6 you need to multiply it by 3. Whatever you do at the bottom, you do at the top, so the fraction would be 15/18 now you just need to add them up in which you get 16/18 but if need to simplify it, you need to divide it by 2 which is 8/9
So the answer is 8/9
Hoped this helped! :)
The answer to this question is 10 units
Since the whole set is composed of a total of 55 people, with 45 people being drinks of either coffer or tea, then the remaining people not included in the 45 would be the non-drinkers. So 55-45, meaning there are 10 people who drink neither tea nor coffee. To obtain the probability:
10/55 = 2/11 = 0.182
Therefore, the probability of a person being picked at random does not drink either coffee or tea is 0.182.
