I believe in standard form this would be 31/2 + 27i/2
ANSWER:
The probability is 1/43680
STEP-BY-STEP EXPLANATION:
We have the following:
0. The probability that Morgan is chosen first = 1/16. Now there are 15 students left after this.
,
1. The probability that Harmony is chosen second = 1/15. Now there are 14 students left after this.
,
2. The probability that Kenny is chosen third = 1/14. Now there are 13 students left after this.
,
3. The probability that Ben is chosen fourth = 1/13.
Therefore, the required probability is:
Difference-of-Squares Formula:
For a difference of squares a2 – b2, the factorization is:
(a – b)(a + b)
