)two players, a and b, alternatively and independently toss a coin and the first player to obtain a head wins. assume, player a tosses first and that p(‘head’) = p. (a) what is the probability that a wins? (b) show that for all p ∈ (0, 1), p("a wins") > 1/2.

Answer with Step-by-step explanation:

Part a)

Player A wins as follows:

1) He wins during the first toss itself.

2)Player A losses and then Player B also losses his turn and Player A wins subsequently

Probability of event 1 is 'p' (Given)

thus we have

Part b)

We have

Thus for least value put p = 0

Thus

lol we need to see what the question is asking about

step-by-step explanation:

you have to wait a while to reward brainliest if only one person answers. if 2 people answer there should be a "mark brainliest" on their question.
