Answer 2

hw do u approach probability questions?

Answer 3

any insights by meverett

Answer 4

well the last two questions that you have asked, have been completely different.

For your first question, I would use the underline method. If we roll the dice once, we need one fraction

_____

If we roll the dice twice, then we need two fractions multiplied together

_____ ______

If we roll the dice thrice, then we need three fractions multiplied together

_____ ______ _______

Answer 5

For your second question it is an expected value, so we see how many outcomes...... two ....... win or lose, so two blank lines


______ _______
win lose


but we need a probability for each as well as the amount won or loss

winning = 1/2 chance since 1/2 the numbers are even

or

winning = (1/2) Rs2

and

losing = - (1/2) Re1

notice the negative sign for losing

Answer 6

okay......

Answer 7

each of these questions that you are studying, cover a wide range of probability, probably to become the most successful at probability we will need practice at several of the same type of questions for awhile. Is this a review section that you are working on? A challenge section?
