एउटा बासकमा 6 ओटा सेता र 10 ओटा काला उस्तै र उत्रै बलहरू छन् । दुई ओटा बलहरू एकपछि अर्को गरी पुनः राखेर भिकिएका छन् ।
A box contains 6 white and 10 black balls of same shape and size. Two balls are drawn at random one after another with replacement.
(a) यदि A र B दुईओटा अनाश्रित घट्नाहरू भए सम्भाव्यताको गुणन सिद्धान्त लेख्नुहोस् ।
If A and B are two independent events, write the multiplication law of probability.
(b) सबै सम्भावित परिणामहरूको सम्भाव्यतालाई वृक्षचित्रमा देखाउनुहोस् ।
Show the probability of all the possible outcomes in a tree diagram.
(c) दुवै बल उही रङ्का पर्ने सम्भाव्यता पत्ता लगाउनुहोस् ।
Find the probability of getting both balls of same color.
(d) दुवै बल फरक रङ्का पर्ने सम्भाव्यता, दुवै बल सेता रङ्का पर्ने सम्भाव्यता भन्दा कति कम वा बढी हुन्छ ? पत्ता लगाउनुहोस् ।
By how much the probability of getting both balls of different color is less or more than probability of getting both balls of white color? Find it.
