A bag has index cards with the following numbers on them: 4, 11, 13, 25, 12, and 18. If an index card is drawn randomly , what is the probabilty that a composite number will NOT be drawn? Finish the following expression: 1 - ____
Answer:
Number will be of the form a=4q+1
Example: 13,17,21,......
Step-by-step explanation:
We have been given that we have remainder 1, divisor 4
So, we can take many numbers which is 1 greater than the multiple of 4.
the numbers will be of the type:
a=4q+1
We can use Euclidean division algorithm
a=bq+r
Here, b is 4, q we will consider we will consider q>=3
So, let q=3
We will get
a=4(3)+1=13
Put q=4
a=4(4)+1=17
There are many numbers.
