A combination lock has 3 wheels, each numbered from 0 to 9 guess the combination by writing five different numbers from 0 to 999 on a piece of paper. Find the probability that the correct combination is written on the paper.

Step-by-step explanation:

Given that the probability of a written event is:

P =

Guessing the combination by writing 5 different numbers, from 0 to 999, on a piece of paper. There are therefore 5 different possible outcomes to this.

However, there is only one correct combination written on the paper which is actually the only favorable outcome.

Probability of event = =

Therefore, the probability that the correct combination is written on the paper is .

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
