$A$ game consists of tossing a one rupee coin $3$ times and noting its outcome each time. Hanif wins if all the tosses give the same result,i.e.,three heads or three tails,and loses otherwise. Calculate the probability that Hanif will lose the game.

$A$ die is thrown once. Find the probability of getting:
$(i)$ a prime number;
$(ii)$ a number lying between $2$ and $6$;
$(iii)$ an odd number.

One card is drawn from a well-shuffled deck of $52$ cards. Find the probability of getting:
$(i)$ a king of red colour
$(ii)$ a face card
$(iii)$ a red face card
$(iv)$ the jack of hearts
$(v)$ a spade
$(vi)$ the queen of diamonds

$A$ game of chance consists of spinning an arrow which comes to rest pointing at one of the numbers $1, 2, 3, 4, 5, 6, 7, 8$ (see figure),and these are equally likely outcomes. What is the probability that it will point at:
$(i)$ $8?$
$(ii)$ an odd number?
$(iii)$ a number greater than $2?$
$(iv)$ a number less than $9?$

Which of the following experiments have equally likely outcomes? Explain.
$(i)$ $A$ driver attempts to start a car. The car starts or does not start.
$(ii)$ $A$ player attempts to shoot a basketball. She/he shoots or misses the shot.
$(iii)$ $A$ trial is made to answer a true-false question. The answer is right or wrong.
$(iv)$ $A$ baby is born. It is a boy or a girl.

$A$ jar contains $24$ marbles,some are green and others are blue. If a marble is drawn at random from the jar,the probability that it is green is $\frac{2}{3}$. Find the number of blue balls in the jar.
