Asecurity alarm requires a four-digit code. the code can use the digits 0–9 and the digits cannot be repeated. what is the approximate probability that the code only contains odd numbers?
0.0005
0.00099
0.012
0.02381

 0.02381

Step-by-step explanation:

Given: A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.

The total number of ways to make security alarm will be  (without repetition) :

If we take only odd numbers then the number of ways to make security alarm will be (without repetition):

Now, the probability that the code only contains odd numbers will be

the answer is a

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
