Question 860145: A binomial probability experiment is conducted with the given parameters. Use technology to find the probability of x successes in the n independent trials of the experiment.
n=6, p=0.35, x=<4
P(X<4)=
somehow, i'm getting totally confused because of the "<" rather than x just being "4." thanks, ahead of time, for showing all steps. pearsonmylab usually shows all steps, but in this case, i'm just not figuring it out. i do not use a graphing calculator. i only use statcrunch, and have no clue how to use it in this case. but writing every step out would be much appreciated so i can finish and learn my homework. thanks.

Hi,
good to hear You have the 'tools' with statcrunch
Binomial
n=6, p=0.35, x=<4
P(X<4)= see 3a)
P(X<4) = .8826 (for Your reference) recommend stattrek.com as a good back Up

1. Select the name of the desired distribution
from the menu listing
(e.g., Binomial, Normal, etc.).
2. In the first line below the plot in the
calculator window, specify the distribution
parameters. As examples, with
the normal distribution, specify the
mean and standard deviation or with
the binomial distribution, specify n
and p.
3. In the second line below the plot,
specify the direction of the desired
probability.
a. To compute a probability, enter a value to the right of the direction
selector and leave the remaining field empty
(e.g.,P(x<3) = ___ ).
b. b. To determine the point that will provide a specified probability, enter the probability to the right of the direction selector and leave the
other field empty (e.g.,P(X>___ = .25 ). This option is available only for continuous distributions.
4. Click Compute to fill in the empty fields and to update the graph of the distrib
