4. I have a box with 40 tickets: 37 marked [1], 1 marked [2], 1 marked [3], and 1 marked 38 For each part of this question, use normal approximation if you think it is appropriate (look up area on table or use calculator). If you don't think it's appropriate say why not and if possible find the chance in some other way. (a) In 30 draws, find the chance that the sum of draws is 30 or less. (b) In 40 draws, find the chance that the sum of the odd numbers is 43 or more. (c) Write a line of code in R that will answer the following question as accurately as possible. In 50 draws, find the chance that the number of times I draw a 1 is 43 or more.
