Exercise 15.1

1. In a cricket match, a batswoman hits a boundary 6 times out of 30 balls she plays. Find the probability that she did not hit a boundary.

Answer

Total numbers of balls = 30
Numbers of boundary = 6
Numbers of time she didn't hit boundary = 30 - 6 = 24
Probability she did not hit a boundary = 24/30 = 4/5

2. 1500 families with 2 children were selected randomly, and the following data were recorded:
Number of girls in a family210
Number of families           475                    814                  211       
Compute the probability of a family, chosen at random, having
(i) 2 girls                (ii) 1 girl                   (iii) No girl
Also check whether the sum of these probabilities is 1.

Answer

Total numbers of families = 1500

(i) Numbers of families having 2 girls = 475
Probability = Numbers of families having 2 girls/Total numbers of families
                  = 475/1500 = 19/60
(ii) Numbers of families having 1 girls = 814
Probability = Numbers of families having 1 girls/Total numbers of families
                  = 814/1500 = 407/750
 (iii) Numbers of families having 2 girls = 211
Probability = Numbers of families having 0 girls/Total numbers of families
                  = 211/1500
Sum of the probability = 19/60 + 407/750 + 211/1500
                                     = (475 + 814 + 211)/1500 = 1500/1500 = 1
Yes, the sum of these probabilities is 1.

प्रश्न अभ्यास

कहानी से

1. केशव और श्यामा के मन में अंडों को देखकर तरह-तरह के सवाल क्यों उठते थे?

उत्तर

केशव और श्यामा के मन में अंडों को देखकर तरह-तरह के सवाल इसलिए उठते होगें क्योंकि उन्होंने ऐसा पहले कभी नहीं देखा था। वे अंडों के बारे में जानना चाहते थे।

2. अंडों के बारे में दोनों आपस ही में सवाल-जवाब करके अपने दिल को तसल्ली क्यों दे दिया करते थे?

उत्तर

केशव और श्यामा दोनों आपस ही में सवाल-जवाब करके अपने दिल को तसल्ली दे दिया करते थे क्योंकि उनके प्रश्नों का उत्तर देनेवाला कोई नहीं था। न अम्मा को घर के काम-धंधों से फ़ुरसत थी न बाबू जी को पढने-लिखने से।

3. अंडों के टूट जाने के बाद माँ के यह पूछने पर कि - 'तुम लोगों ने अंडों को छुआ होगा।' के जवाब में श्यामा ने क्या कहा और उसने ऐसा क्यों किया?

उत्तर

माँ के पूछने पर श्यामा ने कहा कि भइया ने अंडों को छेड़ा था क्योंकि उसे लगा भइया ने ही शायद अंडों को इस तरह रख दिया कि वह नीचे गिर पड़े। इसकी उसे सजा मिलनी चाहिए।

4. पाठ के आधार पर बताओ कि अंडे गंदे क्यों हुए और उन अंडों का क्या हुआ?

उत्तर

केशव के छूने से चिड़िया के अंडे गंदे हो गए और इसलिए चिड़िया ने उन्हें नहीं सेया। चिड़िया ने उन अंडों को गिरा दिया और वे बर्बाद हो गए।

पृष्ठ संख्या: 25

5. सही उत्तर क्या है?
अंडों की देखभाल के लिए केशव और श्यामा धीरे से बाहर निकले क्योंकि - 
(क) वे माँ की नींद नहीं तोड़ना चाहते थे।
(ख) माँ नहीं चाहती थीं कि वे चिड़ियों की देखभाल करें।
(ग) माँ नहीं चाहती थीं कि वे बाहर धूप में घूमें।
► (ग) माँ नहीं चाहती थीं कि वे बाहर धूप में घूमें।

6. केशव और श्यामा ने चिड़िया और अंडों की देखभाल के लिए किन तीन बातों का ध्यान रखा?

उत्तर

केशव और श्यामा ने चिड़िया और अंडों की देखभाल के लिए उनके आराम का, धूप से बचाने का और खाने का ध्यान रखा। आराम के लिए कपड़ा बिछाया, धूप से बचाने के लिए टोकरी से ढक दिया और खाने के लिए पास में दान और पानी की प्याली रखी।

7. कार्निस पर अंडों को देखकर केशव और श्यामा के मन में जो कल्पनाएँ आईं और उन्होंने चोरी-चुपके जो कुछ कार्य किए, क्या वे उचित थे? तर्क सहित उत्तर लिखो।

उत्तर

कार्निस पर अंडों को देखकर केशव और श्यामा के मन में जो कल्पनाएँ आईं और उन्होंने चोरी-चुपके जो कुछ कार्य किए, वे अनुचित थे। वे मदद तो करना चाहते थे परन्तु उनके पास जानकारियों का अभाव था इसलिए उन्होंने जितने भी कार्य किये, वो गलत थे।

8. पाठ से मालूम करो कि माँ को हँसी क्यों आई? तुम्हारी समझ से माँ को क्या करना चाहिए था?

उत्तर

माँ को बच्चों की नादानी व अज्ञानता पर हँसी आ गई। मेरी समझ से माँ को हँसने के बजाय उन्हें समझाना चाहिए था ताकि वो भविष्य में इन सब चीज़ों के प्रति सतर्क रहें।

कहानी से आगे

3. माँ के सोते ही केशव और श्यामा दोपहर में बाहर क्यों निकल आए? माँ के पूछने पर भी दोनों में से किसी ने किवाड़ खोलकर दोपहर में बाहर निकलने का कारण क्यों नहीं बताया?

उत्तर

माँ के सोते ही केशव और श्यामा दोपहर में चिड़िया के अंडो के लिए टोकरी और दाना-पानी रखने के लिए बाहर निकल आए। बताने पर उन्हें पिटाई का डर था इसलिए माँ  के पूछने पर भी दोनों में से किसी ने किवाड़ खोलकर दोपहर में बाहर निकलने का कारण नहीं बताया।

उत्तर

अच्छा - दीपक एक अच्छा लड़का है।
