1. two cities have nearly the same north-south line of 98 degrees west. The latitude of the first
city is 28 degrees North and the latitude of the second city is 36 degrees north. Approximate the
distance between the cities if the average radius of Earth is 6400 km.
The cities are approximately ______ kilometers apart
Solution
They are 8 degrees apart. So we need to find how far the 8 degrees is in km
The there are 360 degrees total, and the circumference is 2pi*r = 2*pi*6400 = 40212 km
Now multiply by 8/360
8/360 * 40212 = 894 km.

1. 1. Two coins are tossed. Find the probability that one coin is a head and the other is a tail.
Choices:
A. 1/8
B. 1/2
C. 1
D. 1/4
Solution
Option B .
Since, no. of events will be {HH , HT , TH , TT} ; were H is heads & T is Tail
& getting one coin head & other as tail is 2.
So Probability of getting one coin head & other as tail is 2/4 = 1/ 2.................
