graders, 489 are 10th graders, 514 are 11th grades, and the rest are 12th graders. The
ASB needs 8 students for a "Virtual Ice Breaker Game". Find the probability
a) All 8 students are seniors.
b) At least 1 freshmen.

Expert Solution

Step 1

From provided information:

Santa Fe high school has 2071 students. 561 are 9^th graders (Freshmen), 489 are 10^th graders, 514 are 11^th graders and 507 are 12^th graders.

The ASB needs 8 students for virtual ice breaker game.

a) Probability that all 8 students are seniors can be calculated using combination method as follows:

$\begin{array}{rcl} P & = & \frac{{}^{507}C_{8}}{{}^{2071}C_{8}} \\ = & 0.00001237 \end{array}$

Probability that all 8 students are seniors is 0.00001237.
