Since there are 22 participants all in all. The possible combinations of the two picked for practice first is,
22C2 = 231
The probability of picking one from each gender will be solved through the calculation below.
(10C1)x(12C1) / 231 = 40/77
In percentage, the answer would be approximately 52%. Thus, the answer is the first choice.
40x = 1500
x = 37.5
37.5% i believe
Answer:



Step-by-step explanation:
Given
The attached figure


Solving (a): EF
Since m is a perpendicular bisector, then <EGF and <EGH are right-angled.
So, EF will be calculated using Pythagoras theorem which states:




Take the positive square roots of both sides


Solving (b): GH
Since m is a perpendicular bisector, then GH = FG



Solving (c): EH
Since m is a perpendicular bisector, then EH = EF
