An Internet packet is sent from its source to Router 1, then from Router 1 to Router 2 and, finally, from Router 2 to its destination. Assess the probability that a packet is successfully transmitted from the source to the destination if we know that the routers drop packets independently, each with probability 0.01.

What I think is that the probability of each router successfully transmit the packet is P(R1) = P(R2) = 1 – 0.01 = 0.99
And the probability of packet successfully transmit from resource to destintion though two routers is:
P(R1 intersect R2) = 0.99 x 0.99 = 0.9801

However I am not sure about my answer, I am a little bit confused about when the router drop the packet, will it drop between router 1 and router 2 or not.
