Question 36314This question is from textbook Algebra 1
: Please help me on this probability problem. To raise money the music club has set up a lottery using 2 digit numbers. The first digit will be from 1 to 4. The second digit will be from 3 to 8. Trudy's first digit is 2 and she can't remember the second digit. If only one two digit lottery winner is drawn, and that number has a 2 for the first digit, what is the probability that Trudy will win? I tried and got no where with this one. This question is from textbook Algebra 1

SEEING AS SHE HAS THE FIRST NUMBER HER ODDS ARE NOW 1 IN 6 CHANCES OF MATCHING HER SECOND NUMBER 1/6 OR HER SUCCESSES ARE 1 OUT OF A TOTAL SET OF 7 NUMBERS.
1/6=16 2/3% OF WINNING.

If the winning number has a "2" as its 1st digit,
and Trudy has selected a "2" as her 1st digit,
Judy will win if her 2nd digit matches the 2nd
digit of the winning number.
The 2nd digit can only be 6 different digits.
So the probability that Trudy will win is 1/6.
