98 points in total! 1 question! no calculator! show your work! a student randomly guesses on 10 true or false questions. use the binomial model to determine the probability that the student gets 5 out of the 10 questions right. show all your steps.

0.2460 is the required probability.

Step-by-step explanation:

 We have been given binomial model

n is the total number of questions which is 10

x is the questions taken out to be which is 5

p is the probability of right answers which is :

q is the probability of the false answers which is :

We will use the model by substituting the values we get:

on substituting the values we get:

Cancel out the common terms from numerator and denominator we get:

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
