Answer: the probability is 0.25
Step-by-step explanation:
We have 10 numbers:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Of those, the odd ones are:
1, 3, 5, 7, 9
So we have 5 odd numbers.
The probability that the outcome is an odd number is equal to the number of odd numbers divided the total number of numbers:
p = 5/10 = 0.5
For the second spin the probability is the same, p = 5/10, because the first outcome does not affect the results of the second spin.
The probability of spining an odd number both times, then is the joint probability for two times this same event:
P = (5/10)(5/10) = 0.5*0.5 = 0.25
or 25% in percent form
Answer:
X= 24+7/8 | Y= 24-8x
<u>Steps for answers:</u>
<u>For X:</u>
1. Add y to both sides.
-8x=24+y
2. Divide both sides by -8.
x=-24+y/8
-----------------
<u>For Y:</u>
1. Add 8x to both sides.
-y=24+8x
2. Multiply both sides by -1.
y=-24-8x
