Athree-digit personal identification number is chosen using the digits 19. the digits cannot be repeated. what is the approximate probability that the first digit will be 6? 0.00595 0.03571 0. 0.7

Step-by-step explanation:

Given that there are 19 digits.  Out of these, a three digit personal identification number is chosen.  There is no repitition of digits.

Total number of digits that can be selected out of 19 digits without repitition

=19P3

=19(18)(17)

Total number of digits that can be selected with 6 as first digit

= Number of selecting 2 digits from the remaining 18 digits without repitition

=18(17)

Hence required probability

= probability that the first digit will be 6

=

c is the answer

step-by-step explanation:

r and t.

both are 64 degrees.
