In a non leap year find probability of 53 Mondays and 53 tuesdays

Posted by Priyanka Sharma 4 years, 5 months ago

CBSE > Class 11 > Mathematics

1 answers

Gaurav Seth 4 years, 5 months ago

Non Leap year has 365 days

365days = 52 weeks + 1 day

Since, There are 52 weeks in a non leap year,

Therefore, There are minimum 52 Tuesday.

Now 1 additional day can be :

{ M , T , W , Th , F , Sa , S }
n(S) = 7

Probability of getting 53 Tuesday = Probability of getting Tuesday as extra day

So, P = 1/7

Find the equation of the set of point which are equidistant from the point (1, 2,3) and (3, 2,-1)

Posted by Prince Jangra 4 years, 5 months ago

CBSE > Class 11 > Mathematics

2 answers

Yogita Ingle 4 years, 5 months ago

Let A(1,2,3)andB(3,2,-1) are the given points and P(x,y,z) is the point that is equidistant from these two points.
Then, PA=√(x-1)²+(y-2)²+(z-3)²
PA=√x²+y²+z²-2x-4y-6z+14
PB=√(x-3)²+(y-2)²+(z+1)²
PB=√x²+y²+z²-6x-4y+2z+14
As, we are given, PA=PB
∴√x²+y²+z²-2x-4y-6z+14
=√x²+y²+z²-6x-4y+2z+14
⇒x²+y²+z²-2x-4y-6z+14
=x²+y²+z²-6x-4y+2z+14
⇒4x=8z
⇒x-2z=0, which is the required equation.
