Question

c) if you were to draw a histogram for the number of heads, what shape would it be?
select an answer
left - skewed
bell - shaped
right - skewed

Explanation:

When flipping a fair coin multiple - times, the distribution of the number of heads follows a binomial distribution. For a binomial distribution with a reasonable number of trials, it approximates a normal (bell - shaped) distribution. This is due to the Central Limit Theorem which states that the sum of a large number of independent and identically distributed random variables will be approximately normally distributed. In the case of coin flips, each flip is an independent Bernoulli trial, and the number of heads is the sum of these trials.

Answer:

Bell - shaped
