If three coins are tossed, represent the sample space and the event of getting atleast two heads, then find the number of elements in them.

One ticket is drawn at random from a bag containing 24 tickets numbered 1 to 24. Represent the sample space and the event of drawing a ticket containing number which is a prime. Also, find the number of elements in them.

Ten coins are tossed. Then what is the probability of getting atleast 8 heads ?

The probability of getting exactly two heads when tossing a coin three times is

Nine balanced coins tossed together once. Find probability of getting at least 6 heads.

1 to 7, describe the sample space for the indicated experiment. A coin is tossed three items.

A coin is tossed four times write the elements of sample space.

A coin is tossed three times is succession. If E is the event that there are at least two heads and F is the event in which first throw is a head, then P(E | F) = ………

Three coins are tossed once. Let A denote the event 'three heads show", B denote the event "two heads and one tail show", C denote the event" three tails show and D denote the event 'a head shows on the first coin". Which events are (i) mutually exclusive? (ii) simple (iii) Compound?
