A certain coin lands head with probability p. Let Q denote the probability that when the coin is tossed fourtimes the number of heads obtained is either 0 or 2 or 4. Then

A certain coin lands head with probability p. Let Q denote the probability that when the coin is tossed fourxx the number of heads obtained is either 0 or 2 or 4. Then

A certain coin is tossed with probability of showing head being 'p' . Let 'q' denotes the probability that when the coin is tossed four times the number of heads obtained is even. Then

A certain coin is tossed with probability of showing head being 'p' . Let 'q' denotes the probability that when the coin is tossed four times the number of heads obtained is even. Then

A certain coin is tossed with probability of showing head being 'p' . Let 'q' denotes the probability that when the coin is tossed four times the number of heads obtained is even. Then (a) there is no value of p , if q=(1)/(4) (b) there is exactly two value of p , if q=(3)/(4) (c) there are exactly three value of p , if q=(3)/(5) (d) there are exactly four value of p , if q=(4)/(5)
