Astudent randomly guesses on 10 true/false questions. use the binomial model to determine the probability that the student gets 5 out of 10 questions right. show all your steps.

Step-by-step explanation:

we are given

A student randomly guesses on 10 true/false questions

so,

there only true and false

so, probability getting true question is

so, probability getting false question is

the student gets 5 out of 10 questions right

so,

r=5

we can use binomial probability formula

now, we can plug values

we can simplify it

and we get

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
