A bird eats two types of worms, P and Q, picking them randomly. Which one of the following describes the kind of probability distribution of the number of worms of type P eaten by the bird in a day?
Show Hint
- Binomial
- Normal
- Log-normal
- Uniform
The Correct Option is A
Solution and Explanation
Step 1: Understanding Binomial Distribution.
A binomial distribution models the number of successes (in this case, the number of type P worms eaten) in a fixed number of independent trials (the total number of worms eaten), with two possible outcomes (P or Q worm).
Step 2: Explanation of the other options.
The Normal distribution is used for continuous data and is not suitable for discrete outcomes like counting the number of type P worms.
Log-normal distribution applies to data that is log-transformed and does not describe counts of events.
Uniform distribution assumes equal probability for all outcomes, which doesn't apply here since the bird is choosing between two types of worms.

- An organization allows its employees to work independently on consultancy projects but charges an overhead on the consulting fee.
The overhead is 20% of the consulting fee if the fee is up to ₹5,00,000.
For higher fees, the overhead is ₹1,00,000 plus 10% of the amount by which the fee exceeds ₹5,00,000.
The government charges a Goods and Services Tax (GST) of 18% on the total amount (i.e., the consulting fee plus the overhead).
An employee of the organization charges this entire amount — that is, the consulting fee, overhead, and tax — to the client.
If the client cannot pay more than ₹10,00,000, what is the maximum consulting fee that the employee can charge?

After the 2nd round, the 5th student behind Q leaves the game.
After the 3rd round, the 3rd student behind V leaves the game.
After the 4th round, the 4th student behind U leaves the game.
