Question

according to a census, 3.3% of all births in a country are twins. if there are 2,500 births in one month, calculate the probability that more than 90 births in one month would result in twins. use a ti-83, ti-83 plus, or ti-84 calculator to find the probability. round your answer to four decimal places. provide your answer below:

Answer 1

To calculate the probability that more than 90 births in one month would result in twins, we can use the binomial probability formula. Use a TI-83, TI-83 Plus, or TI-84 calculator to find the probability.

Step-by-step explanation:

To calculate the probability that more than 90 births in one month would result in twins, we can use the binomial probability formula. The formula is:

P(x > n) = 1 - P(x ≤ n)

where P(x > n) is the probability of getting more than n successes, P(x ≤ n) is the cumulative probability of getting n or fewer successes. In this case:

p = 0.033, n = 90, and N = 2500.

Now, we can use a TI-83, TI-83 Plus, or TI-84 calculator to find the cumulative probability.
