At a carnival entrance, tickets are assigned seven-digit numbers using the digits 0-5. If one ticket number is chosen randomly for a prize, what is the probability that every number on the ticket is even

"0.0041" is the right answer.

Step-by-step explanation:

According to the question,

The total possible number of tickets will be:

=

=

here,

The total even numbers are:

=

i.e., (2, 4)

now,

With even numbers, the total number of tickets are:

=

=

hence,

The probability will be:

=

=

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
