A thief steals an ATM card and must randomly guess the correct three-digit pin code from a 7-key keypad. Repetition of digits is allowed. What is the probability of a correct guess on the first try? The number of possible code is__?? (Type an integer or fraction. Simplify your answer) The probability that the correct code is given in the first try is __?? (Type an integer or fraction. Simplify your answer.)

1/343

Step-by-step explanation:

Given that:

Required pass code = 3 digit long

Digit or keypad option / length = 7

What is the probability of a correct guess on the first try? To obtain this,

Probability = required outcome / Total possible outcomes

The required outcome = correct guess; which is a single combination of the right digits = 1

Total possible outcomes = number of available combinations or the number of possible codes = (7^3) = 343

Hence,

P(right guess on first try) = required outcome / Total possible outcomes

= 1/343

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
