Mary had a chance to select a number from 1 to 20 randomly. What is the probability that the number is divisible by 3? ​

The answer is 9 because it is divisible by 3

Step-by-step explanation:

9/3=3

6/20 = 3/10

Step-by-step explanation:

There are 6 numbers divisible by 3 between 1-20

Being: 3 6 9 12 15 18

With that information, we know that there are 6 numbers out of 20 that are possible to meet the criteria, hence, the chances of Mary getting a number divisible by 3 is 6/20, or 3/10 simplified.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

the answer for the question that you are asking is 4
