A fair coin is tossed once. Find the probability of getting a head.
Answer
Step 1: A fair coin has 2 equally likely outcomes: Head and Tail. Step 2: Outcomes favourable to head = 1. Step 3: Total possible outcomes = 2. Step 4: Use P(E) = Number of outcomes favourable to E / …
एक निष्पक्ष सिक्का एक बार उछाला जाता है। हेड आने की प्रायिकता ज्ञात कीजिए।
Answer
चरण 1: एक निष्पक्ष सिक्के के 2 समान रूप से संभावित परिणाम होते हैं: हेड और टेल। चरण 2: हेड के अनुकूल परिणाम = 1. चरण 3: कुल संभावित परिणाम = 2. चरण 4: P(E) = E के अनुकूल परिणामों की संख्या / सभी संभाव…

एक पासा एक बार फेंका जाता है। 4 से बड़ी संख्या आने की प्रायिकता ज्ञात कीजिए।
Answer
चरण 1: एक पासे के 6 समान रूप से संभावित परिणाम होते हैं: 1, 2, 3, 4, 5, 6. चरण 2: 4 से बड़ी संख्याएँ 5 और 6 हैं। चरण 3: अनुकूल परिणाम = 2. चरण 4: कुल परिणाम = 6. चरण 5: P(4 से बड़ी संख्या) = 2/6 = 1/3…
A die is thrown once. Find the probability of getting a number less than or equal to 4.
Answer
Step 1: A die has 6 equally likely outcomes. Step 2: Numbers less than or equal to 4 are 1, 2, 3, 4. Step 3: Favourable outcomes = 4. Step 4: Total outcomes = 6. Step 5: P(number less than or equal to…
एक पासा एक बार फेंका जाता है। 4 से कम या उसके बराबर संख्या आने की प्रायिकता ज्ञात कीजिए।
Answer
चरण 1: एक पासे के 6 समान रूप से संभावित परिणाम होते हैं। चरण 2: 4 से कम या उसके बराबर संख्याएँ 1, 2, 3, 4 हैं। चरण 3: अनुकूल परिणाम = 4. चरण 4: कुल परिणाम = 6. चरण 5: P(4 से कम या उसके बराबर संख्या) =…
