What is the probability of an impossible event darekt answer​

Answer 1

Answer:

Three different coins are tossed together. Find the probability of getting

(i) exactly two heads

(ii) at least two heads

(iii) at least two tails

Step-by-step explanation:

Answer 2

Answer:

P(Getting exactly two heads) = 3 / 8

Possible outcomes when three coins are tossed together:

= 2 * 2 * 2 = 8 Possible Outcomes

Always keep in mind this formula while calculating Probability of an event:

{P(E) = No Of Outcomes / Total No Of Outcomes}

P(E) = No Of Outcomes / Total No Of Outcomes

(i) No of possible outcomes for getting exactly two heads = HHT, HTH and THH.

3 possible outcomes for getting exactly two heads.

P(Getting exactly two heads) = 3 / 8
