<h3>Answer:  1/8</h3>

Explanation:

The only way to get a difference of 2 is to draw a "3" and then a "5" in either order.

The probability of selecting any tile is 1/4. The probability of selecting two particular tiles in a row is (1/4)*(1/4) = 1/16 since we replaced the first tile selected.

2*(1/16) = 1/8 represents the probability of selecting a 3 and 5 in either order.

                               RAP      ROCK     COUNTRY     TOTAL
Grades 9-10           40           30            55                  125
Grades 11-12         60           25            35                  120
TOTAL                    100          55            90                  245

The sum of the row total is equal to the sum of the column total
125 + 120 = 100 + 55 + 90
245 = 245

Four friends ordered a pizza cut into eight slices. The whole pizza was eaten, with each friend eating a different number of sli
raketka [301]

Answer:

{0,1,3,4}

Step-by-step explanation:

Given, total no of slices=8.

Total no of friends=4.

also each friend didnt ate more than the other three.

let a,b,c,d be no of slices ate by the friends 1,2,3,4 respectively.

given sum of a+b+c+d=8.

now applying the second condition

a\leq b+c+d \\b\leq c+d+a\\c\leq a+b+d\\d\leq a+b+c

so each of a,b,c,d must be less than or equal to 4.

which means 5 values are possible{0,1,2,3,4}.from this set you have to select 4 values such that their sum is 8.hence, those values are {0,1,3,4}.
