Describe the sample space for the indicated experiment: A coin is tossed three times.
A coin has two faces: head $(H)$ and tail $(T)$.
When a coin is tossed three times, the total number of possible outcome is $2^{3}=8$
Thus, when a coin is tossed three times, the sample space is given by :
$S =\{ HHH ,\, HHT ,\, HTH ,\, HTT , \,THH , \,THT , \,TTH , \,TTT \}$
Three coins are tossed once. Find the probability of getting no head.
Let $A$ be the event that the absolute difference between two randomly choosen real numbers in the sample space $[0,60]$ is less than or equal to $a$. If $P(A)=\frac{11}{36}$, then $a$ is equal to $...............$.
A bag contains $3$ black and $4$ white balls. Two balls are drawn one by one at random without replacement. The probability that the second drawn ball is white, is
If $A$ is a sure event, then the value of $P (A$ not ) is
The chance of getting a doublet with $2$ dice is
