If you toss 3 dices, what is the chance to get at least one 3?

0.4213

Step-by-step explanation:

For "at least" questions, it is useful to calculate the probability of that event not happening, In this case, the probability of not getting one three (or any specific number). It is quite obvious that for one dice you have a 5/6 chance of not getting a three. For three the probability of not getting a three would then be:

5/6⋅5/6⋅5/6=125/216=0.5787

So the opposite (getting at least one three) would be 1 minus that or 1 - 0.5787 = 0.4213

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
