C) 10.5
D) 11.1
The expression which would determine the probability that both digits are even which is required for bicycle lock is (4P1)(3P1)/(9P2).
The permutation is the arrangement of the things or object in a systematic order, in all the possible ways. The order of arrangement in permutation is in linear.
A bicycle lock requires a two-digit code of numbers 1 through 9, and any digit may be used only once. The probability of choosing 2 digits from 9 is,
There are total 4 even numbers {2,4,6,8}. The probability of choosing first digit's even from 4 even numbers is,
For the second digit to be even is,
Thus, the favorable outcome is, and total outcome is . Thus, the expression which would determine the probability that both digits are even is,
Thus, the expression which would determine the probability that both digits are even which is required for bicycle lock is (4P1)(3P1)/(9P2).
