Card 1Mutually exclusive events

A die is rolled. Let E be the event 'die shows 4' and F be the event 'die shows even number'. Are E and F mutually exclusive?

Answer

Step 1: Write the events. E = {4} F = {2, 4, 6} Step 2: Check common outcomes. E ∩ F = {4} Step 3: Since the intersection is not empty, the events can occur together. Answer: No, E and F are not mutua

Card 2आपसी रूप से अनन्य घटनाएँ

एक पासा फेंका जाता है। मान लीजिए E घटना 'पासा 4 दिखाता है' है और F घटना 'पासा सम संख्या दिखाता है'। क्या E और F परस्पर अनन्य हैं?

Answer

चरण 1: घटनाओं को लिखिए। E = {4} F = {2, 4, 6} चरण 2: उभयनिष्ठ परिणामों की जाँच करें। E ∩ F = {4} चरण 3: चूँकि प्रतिच्छेदन खाली नहीं है, इसलिए घटनाएँ एक साथ घटित हो सकती हैं। उत्तर: नहीं, E और F परस्पर

Card 3Event from sample space

A die is thrown. Find the event 'a number less than 4 appears'.

Answer

Sample space: S = {1, 2, 3, 4, 5, 6} Numbers less than 4 are 1, 2, and 3. Event = {1, 2, 3} Answer: {1, 2, 3}

Card 4नमूना स्थान से घटना

एक पासा फेंका जाता है। घटना '4 से कम संख्या प्रकट होती है' ज्ञात कीजिए।

Answer

नमूना स्थान: S = {1, 2, 3, 4, 5, 6} 4 से कम संख्याएँ 1, 2, और 3 हैं। समt = {1, 2, 3} उत्तर: {1, 2, 3}

Card 5Simple events

For tossing two coins, write the simple events and check how many there are.

Answer

Sample space for two coin tosses: S = {HH, HT, TH, TT} Each simple event has exactly one sample point. So the simple events are: {HH}, {HT}, {TH}, {TT} Number of simple events = 4 Answer: There are 4

Card 6सरल घटनाएँ

दो सिक्कों को उछालने के लिए, सरल घटनाओं को लिखें और देखें कि वे कितनी हैं।

Answer

दो सिक्कों को उछालने के लिए नमूना स्थान: S = {HH, HT, TH, TT} प्रत्येक सरल घटना में ठीक एक नमूना बिंदु होता है। तो सरल घटनाएँ हैं: {HH}, {HT}, {TH}, {TT} सरल घटनाs = 4 की संख्या उत्तर: 4 सरल घटनाएँ है

Card 7Compound events

A coin is tossed three times. Find the event 'exactly one head appears'.

Answer

Step 1: List outcomes with exactly one head. HTT, THT, TTH Step 2: Form the event. E = {HTT, THT, TTH} Answer: {HTT, THT, TTH}

Card 8मिश्रित घटनाएँ

एक सिक्के को तीन बार उछाला जाता है। घटना 'ठीक एक चित आने' का मान ज्ञात कीजिए।

Answer

चरण 1: ठीक एक हेड वाले परिणामों की सूची बनाएं। HTT, THT, TTH चरण 2: घटना बनाएं। E = {HTT, THT, TTH} उत्तर: {HTT, THT, TTH}
