Approximately 10% of people are left-handed. if 15 people are selected at random, what is the probability exactly 2 are left-handed? use the binomialpdf(n, p, x) command on your calculator with the single option for the ti36x-pro. give your answer to 3 decimal places. if you do not have your calculator, you can use the command =binom. dist(x, n,p, cumulative=0).

Probability that exactly 2 left handed people will be selected from 15 people is 0.267

Step-by-step explanation:

We are given the following information:

We treat left-handed people as a success.

P(Left handed people) = 10% = 0.10

The number of people follows a binomial distribution, where

Formula:

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 15 and x = 2

We have to evaluate:

Probability that exactly 2 left handed people will be selected from 15 people is 0.267

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
