Best ResponseYou've already chosen the best response.2Now let's begin. with just one coin toss, what's the probability of getting heads? :D

Best ResponseYou've already chosen the best response.2If it's easier to understand, what are the chances that you get heads with one toss?

Best ResponseYou've already chosen the best response.2Now, the second coin toss would be the same, half or 50% chance of getting heads, yes?

Best ResponseYou've already chosen the best response.2in other words... does the result of the second coin toss depend on the result of the first one?

Best ResponseYou've already chosen the best response.1as if the coin remembers what happened in the previous toss and change its mind to flip the other side in next toss that can never happen

Best ResponseYou've already chosen the best response.1if you just blindly guess the answer, you will get it correct with a probability of 1/4 because there are 4 options

Best ResponseYou've already chosen the best response.0\[\frac{1}{2}\times \frac{1}{2}=\frac{1}{4}\] which is in fact \(\frac{2}{8}\) but not what you want as a final answer

Best ResponseYou've already chosen the best response.0At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors: white, red, green, and blue. There are 10 boxes of each color. All the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color? 10 over 40 multiplied by 9 over 39 10 over 40 multiplied by 10 over 39 10 over 40 plus 9 over 39 10 over 40 plus 10 over 39

Best ResponseYou've already chosen the best response.2hehe forgetting all sentimental attachment to certain box colours, the colour of the candy boxes given away to separate winners don't affect each other, right? IE... they're indpendent? ;)

Best ResponseYou've already chosen the best response.2Okay, so this is a bit of a stretch, so I'm going to lay it out for you. In general, probability is: number of desirable outcomes divided by total number of possible outcomes. With forty boxes and ten white boxes, what's the probability of getting a white box?

Best ResponseYou've already chosen the best response.2\[\Large \frac{\text{number of desired outcomes}}{\text{total number of outcomes}}\] how about now?
