Answer:
For n=6, the given vectors will be collinear.
Step-by-step explanation:
Collinear vectors are the vectors which lie on the same line or parallel lines. In order to find if two vectors are collinear, their ratio is found. If the ratio is same for all unit vectors then the vectors are collinear.
Given
The ratio of first unit vectors is:
In order for the vectors to be collinear the other ratio should also be 1/3
Writing it mathematically
Hence,
For n=6, the given vectors will be collinear.
Answer:
Step-by-step explanation:
Given that a box contains 12 chocolates, 3 of which are white chocolate, 4 milk chocolate, and 5 dark chocolate.
a) the chance that I draw a dark chocolate
b) Given that none of my friends draws a dark chocolate, the chance that I draw a dark chocolate is
since now all 5 dark chocolates would be there and total changed to 9 because 3 friends took 1 each.
c) All four drawn milk chocolates would be
d) the chance that the friend who gets to select first draws a dark chocolate and I draw a dark chocolate too
=P(first friend draws a dark chocolate) * P(I draw a dark chocolate)
When it comes to me chances are either there are 4 dark, or 3 dark, or 1 dark depending upon the other two friends drew black or not
=
