प्रश्न
If \[\bar{E}\] denote the complement or negation of an even E, what is the value of P(E) + P(\[\bar{E}\]) ?
उत्तर
Given: `overlineE`denotes the complement or negation of an event E.
TO FIND: `P(E)+P(overlineE)`
CALCULATION: We know that sum of probability of occurrence of an event and probability of non occurrence of an event is 1.
Hence `P(E)+P(overline E)=1`
Hence the result is `=1`

In fig. 7 is shown a disc on which a player spins an arrow twice. The fraction `a/b` is formed, where 'a' is the number of sector on which arrow stops on the first spin and 'b' is the number of the sector in which the arrow stops on second spin. On each spin, each sector has equal chance of selection by the arrow. Find the probability that the fraction `a/b>1.`
