Answer :

Explanation

From the statement, we know that:

• a jar contains 100 tickets for a drawing,

,

• among those tickets are 7 winning tickets.

We must find the odds in favour of winning.

The odds in favour of winning are:

Odds in favour = Number of successes : Number of failures

In this case, we have:

• Number of successes = 7,

,

• Number of failures = 100 - 7 = 93.

So we have:

[tex]\text{ Odds in favour }=7:93.[/tex]Answer

7:93
