Step-by-step explanation:
Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
The probability of getting a number less than 6 is: 5/8
Step-by-step explanation:
When a 8 sided fair die is rolled the event space is:
S = {1,2,3,4,5,6,7,8}
n(S) = 8
Let A be the event that the number is less than 6
A = {1,2,3,4,5}
n(A) = 5
So,
The probability of getting a number less than 6 is: 5/8
