A student randomly guesses on 10 true/false questions. use the binomial model to determine the probability that the student gets
lana [24]

Answer:

P(5)=\frac{63}{256}

Step-by-step explanation:

we are given

A student randomly guesses on 10 true/false questions

so,

n=10

there only true and false

so, probability getting true question is

p=\frac{1}{2}

so, probability getting false question is

q=\frac{1}{2}

the student gets 5 out of 10 questions right

so,

r=5

we can use binomial probability formula

P(r)=\frac{n!}{r!(n-r)!} p^rq^{n-r}

now, we can plug values

P(5)=\frac{10!}{5!(10-5)!} (\frac{1}{2})^5(\frac{1}{2})^{10-5}

we can simplify it

and we get

P(5)=\frac{63}{256}
