Question

In an attempt to raise money to pay WKU faculty salaries, as state budgets continue to be cut, WKU seeks a solution from its students. For the Fall 2012 registration, students are given an option to pay an extra $20 fee to enter a drawing for a $10,000 stipend toward tuition. If willing, a student pays $20 and is assigned 4 random numbers. 14,000 students pay the fee. On the first day of classes, a large drawing is held, where four random balls are pulled out of a machine of 20 bouncing balls (like the lottery) and two students win $10,000 by virtue of matching their four numbers.. This means that the university made $260,000 and two students were very happy! What was the probability for each student to win a $10,000 tuition stipend? Choose the correct answer using the format of 1 out of the number of possibilities, N. E.g., 1 / N

Explanation / Answer

SO every student had 4 numbers lets say a,b,c,d from 0-9
Also 20 balls were there to draw 4 balls = so total 20C4 combination were ther out of which only 1 is winning SO probability =1/20C4= 1/4845
