Please help Considered numbers (strings) of length 8 over the 10 digits 0, 1, 2...,9 . Suppose that the repetition of the digits is allowed and that the numbers may begin with 0.

(a) how many different numbers are there?

(b) how many of these numbers contain at least two 2s?

(c) what is the probability that a string of length 8 will contain at least two 2s? ​

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
