A dept. store recieves shipment of 23 new radios. There are 5 defective in the shipment. If 4 radios are selected for display, what is the probability that 2 of them are defective?
The number of ways to select the two defective is:
5C2 = 5! / (2!3!)
The number of ways to select the two non-defective is:
18C2 = 18! / (2!16!).
The total number of ways to select 4 radios out of 23 is:
23C4 = 23! / (4!19!)
Multiply and divide to get the probability:
= (5C2)(18C2) / (23C4)
= (10)(153) / (8855)
= 306 / 1771 = .17278373800113
The answer is approximately .17278 or 17.3%
Good luck in your studies,

I have a gateway laptop model number MX6128 and it is not letting me connect to internet. When I try it tells me that the radio is disabled, that I need to enable the radio control switch. I have looked all over for this and even searched the computer help and support but can not find any thing. This is driving me insane. Can anyone tell me how to fix this problem?
there is no radio control switch on a gateway laptop, theres only a Wireless switch and its a button that looks like an antenna
I want to buy a new phone but i don’t want those fancy high tech phones all i want is with 3G and fm radio capabilities
I phone is sick, no regrets!

I am interested in starting an underground radio station online. I need to know how to go about doing this.
You need to go about getting liscenced by the major record labels (which can be quite expensive, as I am currently going thru this), or use a site like live365 (last source cited) which offers a bundle pack that does it automatically.
It really depends on your budget and level of internet expertise. You can do it pretty cheap, though.
I’m thinking of starting an internet radio station; just a personal one and I won’t making money with it. I’ve searched and all I see are laws on profit-making stations and non-profit organizations, still run by some company/school. If an individual like me were to do it, is there any royalty payment needed?
Yes Most Definitely You Would.

I have a problem with my sony mhc-gx250 stereo where for some reason stations 99.5 thru 100.5 will not work. They are not staticky, but rather completely silenced. It is not a problem with the positioning of the antenna or distance from the radio station. Has anyone heard of this problem, and Does anyone know what would fix this?
If everything else works, as it apparently does, it just means you are not able to pick up a signal for a station within those frequency parameters, or no one in you area is even broadcasting between 99.5 and 100.5.
