Answer:
Step-by-step explanation:
There are 6 ways we can roll doubles out of a possible 36 rolls (6 x 6), for a probability of 6/36, or 1/6, on any roll of two fair dice. So you have a 16.7% probability of rolling doubles with 2 fair six-sided dice.
U just need to add row by row
I'll do the first 1: 1+1=2
1+2=3
1+3=4
1+4=5
1+5=6
2.7 = 27/10
27/10 = x/12
cross multiply
10x = 324
divide both sides by 10
x = 32.4
To solve this question, it is needed to know that the sum of the digits of numbers which are multiples of 9 greater than 1, add to 9, that is:
Multiples of 9:
9*1 = 9
9*2 = 18 -> 1 + 8 = 9
9*3 = 27 -> 2 + 7 = 9
9*4 = 36 -> 3 + 6 = 9
9*5 = 45 -> 4 + 5 = 9
Find a number:
Thus, there are 4 possible options for the desired 2-digit number less than 50:
18, 27, 36, 45.
