Answer:
3/32
Step-by-step explanation:
Labels from 1 to 8:
The probability that he gets a number less than 4 (1, 2, 3) is 3/8
The probability to get a multiple of 4 (4, 8) is 2/8 = 1/4
So
The probability that he gets a number less than 4 or a multiple of 4:
= 3/8 x 1/4
= 3/32
Answer
The answer is 5/8.
I saw an answer that gave 3/32, and since I knew that was wrong I wanted to give my answer to not lead others astray.
There are 8 numbers john can pick.
Numbers less than 4 are (1, 2, 3)
Numbers that are a multiple of 4 are (4, 8)
The word "or" in the question implies addition, and adding 3/8 and 2/8 yields a result of 5/8. This is also the answer in the test that I took.
Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9
EX: item cost $100
$100 x 0.9 = $90
Meaning the price of the item after the discount is applied would be $90
1/12
Steps:
1 - 2/3 = 1/3
1/3 / 4 = 1/3 × 1/4 = 1/12
