Which of these expressions entered into a graphing calculator will return the probability that 10 or fewer heads come up when flipping a coin 45 times?

a. binomcdf(45, 10, 0.5)
b. binomcdf(10, 45, 0.5)
c. binomcdf(10, 0.5, 45)
d. binomcdf(45, 0.5, 10)

Option: D is the correct answer.

D.binomcdf(45, 0.5, 10)

Step-by-step explanation:

We are asked to find the probability that 10 or fewer heads come up when flipping a coin 45 times.

We know that the binomial probability distribution function of k successes for n experiments  is given by:

Here we have: n=10

p=flipping of a head=1/2=0.5

k=0,1,2,3,4,5,6,7,8,9,10

i.e. r=10

Now binomcdf is a function which is defined as:

Hence, by putting the values of n,p and r in the function we have:

The binomcdf function is given by:

D.binomcdf(45, 0.5, 10)
