NDA Math Mock Test 03 – Question 100

Question:

The number of ways in which a cricket team of 11 players can be chosen out of a batch of 15 players so that the captain of the team is always included, is:

15 खिलाड़ियों के समूह में से 11 खिलाड़ियों की एक क्रिकेट टीम चुनने के तरीकों की संख्या ताकि टीम का कप्तान हमेशा शामिल रहे, है:

Options:

  • 165
  • 364
  • 1001
  • 1365
  • 165
  • 364
  • 1001
  • 1365

Correct Answer: c)

Explanation:

Since the captain is already selected, we need to choose 10 players from the remaining 14:
\[{}^{14}C_{10} = {}^{14}C_4 = \frac{14 \times 13 \times 12 \times 11}{24} = 1001\]
Hence, the correct option is (c).

कप्तान निश्चित होने के कारण शेष 14 में से 10 खिलाड़ियों का चयन करना होगा:
\[{}^{14}C_{10} = 1001\]
अतः सही विकल्प (c) है।
