First to do this you need to locate the hundredth place which is the second 2. So then use the 5 or higher rule, which is if the number is higher than 5 round up or if it's lower then 5 round down. So 2 is lower than 5 so you would round down giving you the answer of...

Hello from MrBillDoesMath!
Answer:
a = 0, a = 2/5
Discussion:
10a(5a-2) = 0 => A*B = 0 if A or B (or both ) = 0
a = 0 or 5a -2 = 0 =>
a = 0, a = 2/5
Thank you,
MrB
Answer:
The answer is 0.75.
Step-by-step explanation:
To use probability of a complement event, we need to find the situation where none of the couples are sitting next to each other which can happen either two husbands are sitting in the seats 2 and 3 or two wives are sitting in the seats 2 and 3. Also in the first scenario, the wives would need to be sitting at the opposite ends to their husbands and vice versa for the second scenario.
So there are in total 4 scenarios where no couple is sitting next to each other.
There are a total of 16 different ways that they can be seated so the probability of compelement is 16 - 4 = 12, which is 3/4 of the total, meaning that the probability of at least one of the wives sittting next to her husband is 0.75 or 75%.
I hope this answer helps.
The first expression, 12C3, is the right answer. There is no limitation saying that the team must be made up of one student from each year level. Furthermore, no distinction has been made among the three players (no assignments of Boards 1, 2, or 3), as the question just asks how many different groups. Since order does not matter, this is a combination. (If order mattered, this would be a permutation).
