On the last number which is the sixth

On average Drug A reduced symptom by 59% and Drug B reduced them by 63%, this shows that Drug B is more effective. But this comparison isn’t fair because Drug B had less tests done making it have less results which makes the comparison unbalanced. The results from Drug B were also more varied making it appear they’re less effective. Drug B isn’t wrong about it having a greater reduction in symptoms. But some reductions in symptoms in Drug B’s results are extremely high and some are extremely low meaning its performance is inconsistent. Drug B’s reduction in symptoms vary from 16% up to 96% compared to drug A’s 43% up to 71% which makes it more consistent. This supports Drug A’s claim because Drug B has more varied results some as low as 16% which isn’t as effective as Drug A’s 43% making Drug A more effective on average but sometimes can’t produce as effective reductions as drug B% which had a high of 96%. The standard error of drug A dataset is 1.57 Task 2:To win the lottery you have to pick the correct 6 numbers from a total of 49 numbers. So you have to pick the correct first number, then the correct second number, then the correct third number and so on. For the first number you have a 1 in 49 chance if picking the right number so the fraction is 1/49 which is equal to 0.020408. When picking the second number and so on you have less numbers to pick from because you’ve already chosen some previously. When picking the second number you have a 1 in 48 chance which is equal to 0.20833. When picking the third number it’s a 1 in 47 chance which is equal to 0.021277. The fourth number is a 1 in 6 chance which is 0.021739. The fifth number is a 1 in 45 chance which is equal to 0.22222 and the last number which is the sixth number is a 1 in 44 chance which is equal to 0.22727. To calculate the chances of winning you have to multiply all of the fractions together like so. 1/49 x 1/48/ x 1/47 x 1/46 x 1/45 x 1/44 which equals 1/1006834720. This means that your odds at currently winning are 1 in 1006834720. But your chances increase because of the way that the sequence can be written down which is a list of 6 different numbers, this is equal to 720 or 6 factorial. Then you must divide 10068347520 by 720 because of this which equals 1398316. This means that your chances of winning are 1 in 13983816. You have a better chance of finding a pearl in an oyster than winning the lottery which is a 1 in 12000 chance.Buying two lottery tickets will increase your individual chance of winning the lottery by 50% because you have two tickets. This doesn’t increase your chances of winning ticket wise as each ticket will have the same percent chance of being a winning ticket. The chances are doubled because only one of the tickets can be a winning ticket, if both of the tickets could win the lottery then the chances of winning would be less than 50%. If you have to choose six matching numbers from a possible 49 numbers, then there are 49/6 possible draws, the chances of winning with one ticket is the chance that all 6 numbers are the correct numbers so the equation is a 1/ (49/6) chance of winning but with two tickets there’s two chances of
