    Mike Pence suggests the pound difference is set aside and the remaining "Shilling distributed between the tw0" so 5 pence for the cheaper item is the sole solution. The costlier horse is also 5p plus the pound difference = 1.05.

    Get in line Lulu or we who do the Math say Q Ed

    Buckaroo certainly got a bit confused with that teaser. If he is fluent in “david44” the answer should clarify for him.

    Awww.

    Isn't he adorable.
    And funnily enough no answer from Edmundo. Tip, if you need to resort to Bayesian theorem or a calculator, this teaser is not for you.
    Basic logic will provide the answer.

    So 50 results are wrong

    If they are evenly distributed

    Yield 25 false negative or positive each

    So chance for an individual here is 25/1000 = is 0.25% ?

    1/1000

    Before you took the test. Assuming the test taking is random you now have a 95/100 chance that the test is correct.

    Sorry Willy as a doctor you should have got this right, but unfortunately you are wrong. Collect your party hat and balloon on the way out.

    My take on it is that there is a 90.25% chance he has the disease.
    My reasoning
    His result was 1 of 95 that show up positive but of that 95 only 95% are accurate therefore .95 x 95 = 90.25
    Of the negative tests only 95% are also accurate which means there is a 4.75% chance of someone getting a negative test result actually has the disease.

    Just quickly.

    Dyson (Dice on)

    Motorolla

    Canon

    Red Bull

    Colgate (Coal Gate)

    French Connection

    Samsung

    Doctor Pepper

    Kleenex (clean X)




    That's about 30 seconds.

    Which is 20 seconds more that icy's 'teaser' takes.
