Answer:
21 / 143
Step-by-step explanation:
Given that:
Number of Eastern conference reps = 8
Number of western conference rep = 7
Probability of selecting 3 from Eastern reps and 2 from western reps
Probability = required outcome / Total possible outcomes
Total possible outcomes:
selection to be made = 3+ 2 = 5
Total Number of players = 8 +7 = 15
Total possible outcomes
Using combination formula :
nCr = n! / (n-r)!r!
15C5 = 15! / 10!5! = (15 * 14 * 13 * 12 * 11) / (5*4'3*2*1) = 360360 / 120 = 3003
Total possible outcomes = 3003
Required outcome :
8C3 * 7C2
8C3 = 56 ; 7C2 = 21
8C3 * 7C2 = 56 * 21 = 1176
required outcome / Total possible outcomes
= 1176 / 3003
= 21 / 143

Answer c
Step-by-step explanation:
they have to be equivalent
Answer:
D 5/3
Step-by-step explanation:
Secθ= Hypotenuse/Adjacent
Secθ=10/6
Simplify: 10/6 -->5/3
Ans: D 5/3
remember your six trigonometric functions:
Sinθ=Opp/Hyp -->Cscθ=Adj/Hyp
Cosθ=Adj/Hyp -->Secθ=Hyp/Adj
Tanθ=Opp/Adj-->Cotθ=Opp?Adj
It is basically the opposite of each other, don't forget when you are at the last step you simplify! never forget. Also working with square roots will be a bit tricky when converting to Csc/ Sec/ Cot. Just noting you that Square roots don't belong in denominators!
