Answer:
16/33
Step-by-step explanation:
12C4(total possible outcomes)=495
Since there are 6 married couples there must be 6*[2C2×10C2]=270
must subtracted 15 since when there are 2 couples in a group would have doubled 270-15=255
the no of groupings with no married couples 495-255 =240
probability=no of favourable outcomes /no of possible outcome
probability=240/495= 16/33
Answer:
-24
Step-by-step explanation:
Plugging in x=-2, you get:
2(-2)^2+5(-2)=2*4-10= -2
Therefore, f(-2)= -2
tangent
Step-by-step explanation:
because it gave u an angel and and adjacent so your x is the opposite so sin20=x÷17 just use your calculator u will find the ans
