64 movie tickets are sold. 5/8 of the tickets were for adult admission. How many adult admission tickets were sold?
charle [14.2K]

First take note 64 tickets were sold in total and 5/8 of those tickets were for adults.

To solve this you must first make 5/8 a decimal and to do so you will divide 5 by 8.

which is equal to .625

Now multiply 65 by .625

Which will equal 40.42500

So the answer is 40

two dice are rolled in succession. determine the probability that their sum is 10 or more,given that the first die is a 5
MrRa [10]
If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.

Assuming it is a six sided die, the two values that would make this true are 5 and 6.

2 values/6 possible would be a probability of 2/6, which simplifies to 1/3

Final answer: 1/3
