Answer:
The first step would be to look at the first two numbers (which is 27) and estimate which <u>multiple</u> of 5 is closest and <u>below</u> 27.
5*5 = 25
So once she got 25, she will need to subtract 27-25, which will give her 2. REMEMBER: 5 is the first number of the quotient.
Now, she will need to drag the last digit left of 275 (which is 5) to the remainder 2 and think what multiple of 5 will give her the answer 25.
Again, 5*5 = 25
Once again, her numbers on the quotient will be 55. That's the answer.
Answer:
The height is of a cone is 18 cm
For the first roll, the chances of getting any number is 6/6 or 1, since no numbers have been rolled yet.
For the next roll, the chances of getting a different number is 5/6, since 1 number has already been rolled and we don't want to receive the same number.
For the final roll, the chances of getting a different roll from the first 2 is 4/6 or 2/3, since we have already got 2 different numbers that we don't want to repeat.
Now, multiply all these fractions together.
1 * 5/6 * 2/3
= (5*2) / (6*3)
= 10 / 18
= 5 / 9
Thus, you have a 5/9 chance of rolling a different number if you roll the dice three times.
