"That was your equation form, not mine. Mine was neat and orderly, so it didn’t need those brackets.   "

See Nauseated rarely admits when his answers are garbage.  

He will argue that his wrong answers are correct until he is blue in the face.

Nauseated, you do need those brackets - I expect you already know that, but you would not want to lose MORE face would you!

No,no, no,

If such a modification was conducted it would indeed have been by Morgan le’Fay.

This used to be the realm of Camelot.  It was Nauseated himself who dethroned the Queen so he would know.

The Queen has been waiting in exile for some time now for her subjects to rally and reimpose her reign.

Occasionally she sees TitaniumRome and she wonders if he will take up arms on her behalf but then he disappeasrs into the mist again.

Now DragonSlayer554 is back perhaps he can rally some troups.....

She often wonders if  Morgan Tud will help, he could partition Morgan le'Fay to caste a spell over the realm's tyrant. It is Nauseated of whom I speak of course but Tud has a great love affair with his bottle and The Queen thinks that his loyalty to the throne has wavered.   

By his words here it seems that Nauseated may even  prefered the rule of Queen Guinevere to the present chaos that assaults this fine land.

Whinging may not be the right word but neither is bitching!

Maybe we interpret the 2 words slightly differently from one another ://

I was actually surprised because your normal recourse is to blame the poster and say that their question was ambiguous.

Usually you accept zero blame for your wrong answers.  

"Also where do I need the brackets?"

P(not too many people) = 1- (prob of too many people) =  1- [ P(75 turn up)+P(76 turn up)+P(77turn up) ]

NOTE:

Nauseated often rubs me the wrong way and it is good when I can get a little of my own back BUT we are actually quite fond of one another :)

There is nothing like a whinging, CDD afflicted, blind, arthritic, old Troll.

Go eat some more cat food!

"The answer above gives the probablity they will all have a seat."

Well it would do if you added some brackets.   How sad. 

Well, it would be a good answer Nauseated IF you added some brackets.   And IF you were wearing your glasses.  

Would you like to borrow mine?

An airline estimates that 98% of people booked on their flights actually show up. If the airline books 77 people on a flight for which the maximum number is 74, what is the probability that the number of people who show up will exceed the capacity of the plane?

P(too many people show up )

= P(75 turn up)+P(76 turn up)+P(77turn up)

\(=^{77}C_{75}(0.98^{75}*0.02^2) +^ {77}C_{76}(0.98^{76}*0.02^1) + ^{77}C_{77}*(0.98^{77}*0.02^0)\\ =^{77}C_{75}(0.98^{75}*0.02^2) +^ {77}C_{76}(0.98^{76}*0.02) + 0.98^{77}\\\)

The question and answer both look really interesting.  Thanks Heureka :D

Is it a conceptual problem?

The sides are 6 rectangles.

Find the areas of each one and add  them all together.

Hint:

Find b first and then find c afterwards :)
