`n=3`, P (no two consecutive heads appear if first coin shows head)

4 fair coins are tossed and given that the first coin shows head. Find the probability that no two consecutive heads occur on the four coins.

Two unbaised coins are tossed. The probability that the first coin shows 'head' and the second coin shows 'tall' is-

A fair coin is tossed repeatedly until two consecutive heads are obtained. If the probability that 2 consecutive heads occur on fourth and fifth toss is p, then (30)/(p) is equal to

Suppose that two coins are tossed simultaneously Let A be the event that the first coin shows head and B be the event that both coin show tail. Write A and B as sets. Hence, find P (A) and P(B)

Determine P(E/F) Two coins are tossed once E: tail appears on one coin F: one cooin shows head.

Three coins are tossed simultaneously. Find the probability that all coins show heads if at least one of the coins shows a head.

Determine P(E|F) Two coins are tossed once, where E : tail appears on one coin, F : one coin shows head

Determine P(E/F) Two coins are tossed once, where i. E: tail appears on one coin, F: one coin shows head ii E: no tail appears, F: no head appears

Two unbiased coins are thrown together show that the events 1st coin shows a head and 2nd coin shows a head are independent events.
