Answer to Problem R5.1RE
It is expected that 81 percent of all the pieces of toast to land butter side down when it dropped.
Explanation of Solution
Given:
Probability of the toast lands butter side down which is 0.81 or 81%.
Probability of an outcome is the expected frequency of the outcome after several repetitions of the possibility process.
It is expected that 81 percent of all the pieces of toast to land butter side down when it dropped.
(b)
To find: that it more likely that the next piece of toast will land with the butter side up, explain the answer.

Answer to Problem R5.1RE
No
Explanation of Solution
Given:
Probability of the toast lands butter side down which is 0.81 or 81%.
If 4 toasts were dropped and all toasts descended down towards the butter, it makes it no more likely that the next piece of toast will go up the side of the butter, as the toast are independent of each other and therefore each on its own. The probability that a toast falls indicates that it is still equally possible.
