Solution:
Number of times a die is rolled = 20
1 - 3=A
2 - 5=B
3 - 4=C
4 - 2=D
5 - 3=E
6 - 3=F
Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times
= Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes
= 6! × [ 3! × 5! × 4!×2!×3!×3!]
= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]
= 895795200 Ways

Answer:
a) 1/4
b) 0.95
Step-by-step explanation:
0.25 is 25/100, which is 1/4
19/25 is 95/100, which is 0.95
The answer is a. mean. This is the same as the average. (The median is different. It is the number in the middle of all the numbers when they are arranged from smallest to largest. There is no summation or division required in order to determine it.)
Answer:
1/4(x+2) = 3
Step-by-step explanation:
Let's do this one thing at a time.
1/4 of a number means 1/4 times a number. We'll use x to represent "a number," so we have
1/4x
But wait: we need to add 2 to a number (sum = addition). So we have
1/4(x+2)
This is three, so we know that expression is all equal to 3.
1/4(x+2) = 3
