A biased coin has `2/3` probability of landing heads. If the coin is flipped 50 times, then the probability that the total number of heads is even is:

A biased coin has (2)/(3) probability of landing heads.If the coin is flipped 50 xx,then the probability that the total number of heads is even is:

A coin is tossed 3 times. Find the probability distribution of the number of heads.

A coin is biased so that the probability of falling head when tossed is (1)/(4) . If the coin is tossed 5 times , the probability of obtaining 2 heads and 3 tails is

If a coin is flipped twice , what is the probability of the event I head and I tail ?

A biased coin in which probability of getting head is twice to that of tail. If coin is tossed 3 times then the probability of getting two tails and one head is

When a coin is flipped once, what is the probability of getting HEAD ?
