Answer: the normal curve can be used as an approximation to the binomial probability considering the following condition: when the sample is large, in this case n=112
Step-by-step explanation:
for a binomial experiment to be approximated to normal distribution, the following conditions must be present:
i. sample size must be large, in this case sample size is 112
ii. the mean must be equal to np,where n is sample size and p is probability of success
iii. the standard deviation must be equal to npq,where q is the probability of failure
You can learn how to do hard level math by:
-Practicing hard level math
-asking friends who do hard level math to analyze if you have the ability for hard level math
-believing you can do hard level math
-learning from your mistakes :p

Sorry, don’t know the answer
I believe the answer is 2 because 1/2 x 4 = 4/2 =2
