Which expression entered into a graphing calculator will return the probability
that 350 or fewer heads come up when flipping a coin 500 times?​

Respuesta :

Using the a TI-84 calculator, the expression is:

binomcdf(500, 0.5, 350)

The probability of having a or fewer successes, in n binomial trials, each with a p probability of successes is found according to the following expression:

binomcdf(n,p,a)

In this problem:

  • Fair coin, hence [tex]p = 0.5[/tex]
  • The coin is flipped 500 times, hence [tex]n = 500[/tex]
  • 350 or fewer heads, hence [tex]a = 350[/tex]

Then, the expression is:

binomcdf(500, 0.5, 350)
