The radio station manager will award a free stereo to a contest winner. there are 20 black stereos, 15 white stereos, 10 red stereos, and 5 silver stereos to choose from. what is the probability that the stereo randomly selected by the contest winner is not white?

Solution:

we are given that

The radio station manager will award a free stereo to a contest winner. There are 20 black stereos, 15 white stereos, 10 red stereos, and 5 silver stereos to choose from.

we have been asked to find

The probability that the stereo randomly selected by the contest winner is NOT white?

Total number of stereo=50

Total number of white stereo=15

1  can nbe chosen out of 50 in ways.

1  can nbe chosen out of 15 in ways.

So the probability that the chosen sterio is white

So the probability that the chosen sterio isNOT  white

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
