Statistics GCSE edexcel Monday 18th June exam

In my school, I have a Geography exam in the morning that has been moved to 8:30am, I then have the two WJEC German exams that have been moved from 13:15pm to 10:45am and then I am in isolation until 13:15pm when the Statistics exam (2 hours long) is scheduled around the country? :smile:

Bio i think is more important, grade boundaries for statistics are incredibly low - 74% for an A*, and 58% for an A so i wouldn't worry about it , all you need to do is revise the night before hand some of the formulas :smile:

Someone help me out in this question? :/

A company fills tubes with four different coloured sweets.
Each tube is supposed to contain six red, six orange, six brown and six green sweets.
The tubes do not always contain the correct number of each colour of sweets.
It is known that the probability that a tube of these sweets, chosen at random, contains
six green sweets is 0.9
Jacinda buys four tubes of these sweets.
Work out the probability that 3 or more of the tubes contain exactly six green sweets.
(You may use ( p + q)^4 = p ^4 + 4p^3q + 6 p^2q^2 + 4 pq^3 + q ^4 )

It's on the mock paper that my teacher gave me :s-smilie:

P is the probability of getting 6 green sweets and q is the probability of not getting 6 green.

You want at least 3 so you use p ^4 and 4p^3q. Just replace the p with 0.9 and the q with 0.1

So 0.9^4+(4*0.9^3*0.1)=0.9477

That's it.

Someone else already messaged me about it but thank you anyway :biggrin:

I got 28/40, hoping for an A* too :smile:

, glad you can get 71/100 to get A* in exam, but i don't know what we need to get to make up for our low A in the Coursework , hope it's not too high :wink:

P.S i'm just doing a 2010 exam and it's awful...missed out like 10 questions :biggrin:
