The probability of giving birth to a boy is 50%. find the probability that at most there are 3 boys out of 10 births.

1 answer:

5 0

S=Sample Space
n(S)=no. of total outcomes of sample space
= 50%×10=5
n(E)=no. of favourable events=3
Probability of giving birth to boy is,
P(B)=n(E)/n(S)
=3/5....Ans

Which set of rectangular coordinates describes the same location as the polar coordinates (6sqrt 2, 3pi/4)

Sonja [21]

Polar coordinates=(6sqrt 2, 3pi/4)=(r, theta)→r=6 sqrt 2, theta=3pi/4
Rectangular coordinates=(x,y)=?

x=r cos theta=(6 sqrt 2) cos(3pi/4)=(6 sqrt 2)(-sqrt 2 / 2)
x=-3 (sqrt 2)^2=-3(2)→x=-6

y=r sin theta=(6 sqrt 2) sin (3pi/4)=(6 sqrt 2)(sqrt 2 / 2)
y=3 (sqrt 2)^2=3(2)→y=6

Rectangular coordinates of the point = (x,y) =(-6,6)

Answer: Option a. (-6,6)
