I dont get this question it makes no sense
Answer:
Step-by-step explanation:
Consider A=60°, B=50°, C=y°=???
So, according to the measurement of angles of a triangle.
A+B+C= 180°
60°+80°+C= 180°
140°+C=180°
C=180°-140°
C=y°=40°
So, x is also 40° since x and y are vertically opposite angles.
Answer:
0.225
Step-by-step explanation:
Total outcomes of choosing 5 out of 18 members = 18C5
Outcomes of choosing 2 out 11 favourers, 3 out of 7 members = 11C2 & 7C3
Probability = Favourable outcomes / Total outcomes
= ( 11C2 x 7C3 ) / 18C5
<u>[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ] </u>
[ 18 ! / 5! 13! ]
( 55 x 35 ) / 8568
1925 / 8568
= 0.2246 ≈ 0.225
