34% because every time you roll the dice each side has a probability of 17%, so since there are numbers 5 and 6 you want to roll, there is a 34% you will get those numbers. the first roll doesn't have an affect on your next roll
Ok, if you roll the dice once - you'll get: 1, 2, 3, 4, 5 or 6. If you roll it twice, you can get one of these combinations: 1,1 - 1,2 - 1,3 - 1,4 - 1,5 - 1,6 2,1 - 2,2 - 2,3 - 2,4 - 2,5 - 2,6 3,1 - 3,2 - 3,3 - 3,4 - 3,5 - 3,6 4,1 - 4,2 - 4,3 - 4,4 - 4,5 - 4,6 5,1 - 5,2 - 5,3 - 5,4 - 5,5 - 5,6 6,1 - 6,2 - 6,3 - 6,4 - 6,5 - 6,6 Here there are 36 combinations in total. Your chance of getting a 5 and a 2 is 1/36. 5,2 only appears once in this list of possible combinations. 2,5 doesn't count (as 2 would come up first).
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
Step-by-step explanation:
Given
<em></em><em> --- It is negative because he is climbing down</em>
Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.
