A coin is tossed (m+n) times with m>n. Show that the probability of getting m consecutive heads is `(n+2)/2^(m+1)`

A coin is tossed (m+n) xx,(m>n). Find the probability of getting exactly m consecutive heads.

A coin is tossed (m+n) xx,(m>n). Find the probability of getting exactly m consecutive heads.

A coin is tossed n xx.The maximum value of n such that the probability of getting no head is greater than (1)/(16) is

If an unbiased coin is tossed 10 xx then the probability that no two consecutive heads occurs is

A coin is tossed n times . If the probability of getting at least one head is greater than 0.9 then the minimum vaue of n is
