Two particles are moving in a coordinate plane. particle 1 is at the point
and moving along the velocity vector −2
1

particle 2 is at the point −1
1
and moving along the velocity vector
are the two particles going to collide? if so, at
what point, and at what time? assume that time is measured in seconds.

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
