Answer:

The numbers less than 5 are expected to occur 666 times ..

Step-by-step explanation:

First of all, we have to find the probability of rolling a number less than 5 in a single trial

The numbers from 1 to 4 are less than 5 so the probability of rolling a number less than 4 is: 4/6 = 2/3

So,

Expected value = Probability * Number of Trials

= 2/3 * 1000

= 2000/3

= 666 times ..

It takes 2/3 of an hour to paint 2/5 of a room. How long does it take to paint 2/5 of a room?
Lubov Fominskaja [6]

It will take 40 minutes.

To solve, divide 60 by 3. 60 is how many minutes there are in a minute. 3 is how long it takes to paint 2/5 of the room. We do not need to use the number 2/5 in this situation. Now back to 60 divided by 3. The answer is 20 minutes. Now multiply 20 by 2 to get 2/3 of an hour. Therefore, it takes 40 minutes to paint 2/5 of a room.
